Anthropic's Claude reports widespread outage | TechCrunch
Anthropic experienced widespread disruptions on Monday morning, with thousands of users reporting problems accessing Claude services. The outage seems to be affecting Claude.ai as well as Claude Code, though the company said the Claude API is working as intended. Most users experience the error when attempting to log in, as in the screenshot below. "The issues we are seeing are related to Claude.ai and with the login/logout paths," the company's status page reads. Anthropic has not yet detailed what caused the outage, though the company said it has identified an issue and is implementing a fix. The disruption follows an influx of users to Claude, which seems to have benefited from the attention around the company's fraught negotiations with the Pentagon. The chatbot app rose to the top of the App Store charts this weekend, overtaking archrival ChatGPT, after spending a long time below the top 20. U.S. President Donald Trump last week told federal agencies to stop using Anthropic products after a dispute over safeguards preventing the Department of Defense from using its AI models for mass domestic surveillance or fully autonomous weapons. Secretary of Defense Pete Hegseth said he would designate the company as a supply-chain threat, though Anthropic says it hasn't yet received any formal notices.

Is Claude Down? What to Know About the Anthropic AI Outage
Expertise Artificial intelligence, home energy, heating and cooling, home technology. A reported outage for Anthropic's Claude AI has lasted more than two hours Monday morning, with the company saying it was investigating issues and working on fixes for errors on Claude.AI, Claude Code and its Claude Opus 4.6 model. The outage started just before 7 a.m. Eastern Time Monday. Anthropic's status page showed continued errors more than two hours later. Anthropic said in a statement that consumer-facing products were unavailable but that the Claude API, mostly used by businesses, was still working. "Our team is working to restore full service and we'll share updates as we have them," the company said. "We appreciate everyone's patience as we work to bring things back online while experiencing unprecedented demand for Claude over the last week." Downdetector showed reported problems with Claude spiking around 6:45 a.m., with nearly 2,000 reports. That number had dropped to 275 by 9:30 a.m. (Disclosure: Downdetector and CNET are both owned by the same parent company, Ziff Davis.)

Claude outage hits chat, API, vibe coding
Developers ponder the horror of having to actually write code Anthropic's AI service Claude is having artificially intelligent hiccups and availability problems across its basic chat service, API, and Claude Code offering. The outfit's Status Page reports investigations into the problem commenced at 03:15 UTC on March 3rd. In three subsequent updates, the last time-stamped 04:43 UTC, the company again reported "We are continuing to investigate this issue." The Register tried to access the service at 05:10 UTC and was unable to log in. Claude produced the following error message. Anthropic's social media accounts are silent on the matter, but users are filling in the blanks. A common comment laments the fact that Claude going down means developers must revert to their pre-generative-AI habits and actually write some code without assistance. We've also seen folks joyfully join some conspiratorial dots between Claude reportedly being used by the US military to plan its attack on Iran, the subsequent drone strikes that have disrupted operations at Amazon Web Services' facilities in the Middle East, and Amazon's ties to Anthropic.

Anthropic's Claude Chatbot Goes Down For Thousands of Users
Anthropic PBC's popular artificial intelligence chatbot Claude experienced service disruptions on Monday, with thousands of users reporting issues, according to monitoring website Downdetector. The cause of the outage isn't clear. Anthropic said there were "elevated errors" across some services in a status update, and said it began investigating the issue at 11:49 a.m. in London. The outage has affected those who use the Claude chatbot as well as Anthropic's coding service Claude Code, according to the company's status page. Those running apps that have integrated Claude are not experiencing disruption, the company said. The Claude app wasn't working for logged-out users, while social media users posted screenshots on X of an error page describing a "temporary service disruption." "We have identified that the Claude API is working as intended," Anthropic wrote on its status page. "The issues we are seeing are related to Claude.ai and with the login/logout paths." A representative for Anthropic didn't immediately respond to a request for comment. The disruption comes as Anthropic experiences a surge in new users, driven by the company's public-relations feud with the Pentagon. US defense officials want unfettered use of the company's artificial intelligence tools for military purposes, while Anthropic has refused to comply. SpecificallyBloomberg Terminal, the company doesn't want its tools used to surveil US citizens, or for autonomous lethal strikes without a human in the loop. The fight threatens to engulf AnthropicBloomberg Terminal, even if it has popular support, after the Trump administration ordered federal agencies to stop using the company's software, and it was designated a supply-chain risk by the Pentagon. The Claude app has topped Apple Inc.'s App Store for the past few days. Silicon Valley workers have also supported the company's stance. Sam Altman, founder of ChatGPT-maker OpenAI, announced the company had struck a deal with the Pentagon hours after Trump's order.

Anthropic's Claude sees 'elevated errors' as it tops Apple's free apps after Pentagon clash
Claude's status website showed "degraded performance" on Claude Opus 4.6, its latest model released last month. In an update at 9:42 a.m. ET, the site stated that the issue was identified and a fix was in the works. The AI chat app surged in popularity after fallout with the Defense Department over restrictions for the government agency's use of Anthropic's technology. On Friday, President Donald Trump ordered every U.S. government agency to "immediately cease" using Anthropic's technology. Defense Secretary Pete Hegseth announced on X shortly after that the Pentagon would be labeling the company a "supply-chain risk to national security."

Claude crashes under 'unprecedented demand' -- service restored as surge shows explosive growth
Claude is more popular than ever amid OpenAI's deal with the Pentagon Anthropic's Claude chatbot experienced a widespread outage early Monday morning, leaving users unable to access the AI assistant just as its popularity is surging. According to outage reports and Anthropic's status updates, issues began around 5 a.m. ET, peaked shortly after 6 a.m., and were largely resolved later in the morning. Claude's outage comes at a moment when the chatbot is seeing a surge in new users. In recent days, a growing "QuitGPT" movement has encouraged people to cancel ChatGPT subscriptions following backlash over OpenAI's agreement to deploy its models within U.S. defense networks. Anthropic, the company behind Claude, earned praise after reportedly rejecting similar military uses, prompting some users to switch platforms -- and even pushing Claude to the top of app store rankings. What happened That sudden influx of traffic may help explain why the service struggled with users reporting errors loading Claude on web and mobile, as well as failures inside coding tools and integrations, and slow or unresponsive chats. Anthropic said the disruption was caused by "unprecedented demand" and a surge in usage. But while users' access was impacted, reports indicate API and enterprise integrations were mostly unaffected. That distinction suggests backend systems remained stable while consumer-facing services were strained. Why demand is surging The outage comes during a breakout moment for Claude. The platform has surged in downloads and usage in recent weeks as ChatGPT users explore new platforms, developers rapidly adopt it for coding workflows, and enterprises expand integrations. It's clear the AI competition is intensifying across ChatGPT, Gemini and others as more people use AI tools daily. Today's disruption highlights a growing reality of the AI era, underscoring that users are increasingly weighing the companies behind the chatbots, not just what each AI can do. How companies deploy AI and partner with institutions, restrictions and how information is stored and protected are also important to them. Bottom line AI usage is scaling faster than many platforms anticipated -- and right now, a growing number of users are choosing Claude over ChatGPT. As adoption accelerates and more developers, professionals and everyday users migrate their workflows, even leading providers are facing demand pressures similar to the early days of cloud computing and streaming. When millions rely on a single assistant at once, spikes in demand can strain even the most advanced systems.

Claude is down. Here's what Anthropic told us.
Claude, Anthropic's AI chatbot, is experiencing technical issues, the company confirmed on Monday. At 6:49 a.m. ET on Monday, Anthropic posted on its Claude status page that it was investigating "elevated errors" occurring with the Claude chatbot, Claude Opus 4.6 (its latest generation large language model), Claude Console (the Claude developer platform), and Claude Code (the company's AI-powered coding assistant). According to Downdetector, over 2,000 users have reported issues with Claude (Disclosure: Downdetector is owned by Ziff Davis, the same parent company as Mashable.) So, what does Anthropic say the issue is? Anthropic explained to Mashable in a statement that its team was working on a fix, saying: Claude is currently unavailable on our consumer-facing surfaces such as claude.ai and our apps. The Claude API that powers businesses remains unaffected. Our team is working to restore full service and we'll share updates as we have them. We appreciate everyone's patience as we work to bring things back online while experiencing unprecedented demand for Claude over the last week. "We have discovered that some API methods are not working and we are investigating," the company further wrote on the Claude status page, about everything but Claude Opus 4.6. For that LLM itself, Anthropic only said, "The issue has been identified and a fix is being implemented." This level of "unprecedented demand" Anthropic mentioned to Mashable is right. The outage comes after Claude took the number one spot from OpenAI's ChatGPT in Apple's App Store, now the most-downloaded free app in the U.S. (ChatGPT is second, Google's Gemini is fourth).

Anthropic Claude Outage: AI Chatbot Goes Offline Following Trump, Pentagon Blowup - Decrypt
Add Decrypt as your preferred source to see more of our stories on Google. Anthropic's popular Claude AI chatbot platform has been dealing with an extended outage early Monday, with the company confirming issues and saying that it's working on a fix. Users began reporting widespread problems connecting to Claude shortly after 6 a.m. ET, per Down Detector, with Claude's status page showing an acknowledgement of issues soon after. According to the latest update, Anthropic wrote, "The issue has been identified and a fix is being implemented." "Claude is currently unavailable on our consumer-facing surfaces such as claude.ai and our apps," a spokesperson told Decrypt. "The Claude API that powers businesses remains unaffected. Our team is working to restore full service and we'll share updates as we have them. We appreciate everyone's patience as we work to bring things back online while experiencing unprecedented demand for Claude over the last week." The extended downtime comes just days after President Trump instructed U.S. government agencies to stop using the AI platform following disagreements between Anthropic and the Pentagon over how the model could be used for wartime actions. "The United States of America will never allow a radical left, woke company to dictate how our great military fights and wins wars!" Trump wrote on Truth Social on Friday. "That decision belongs to your commander-in-chief and the tremendous leaders I appoint to run our military." The U.S. government will have six months to phase out the software and instead use OpenAI's GPT models, following an agreement announced later Friday. Despite the blowup, Anthropic's Claude was used during U.S. strikes on Iran early Saturday, the Wall Street Journal reported. Anthropic said that it's seen a surge in demand for Claude since the public scuffle, with daily signups breaking records and free users rising 60% since January.

Claude Is Down
President Trump ordered all federal agencies to stop using Anthropic's AI after the company could not come to an agreement with the Defense Department over safety guardrails. If you tried to access Claude for any of your AI needs Monday morning, you might have failed -- or, rather, the chatbot may have failed to load. It's not you, your internet, or your device: Claude is down. Anthropic confirmed the outage on Monday, citing "elevated errors on Claude.ai, console, and claude code." As of this article, the company has posted four updates to Claude's status page: The first, at 11:49 UTC (6:49 a.m. ET), was simply to acknowledge an investigation into the issues; the next, at 12:06 UTC, was an update to confirm continued investigations, before sharing that Claude API was working as intended at 12:21 UTC. At that time, the company had identified the issues were related to Claude.ai and with login and logout paths. Finally, at 13:22 UTC, the company confirmed it had identified the cause of the issue, and a fix is "being implemented," though there's no timeline for how long that might take to roll out to users. Like most outages, I expect Anthropic to get Claude up and running soon. It might be back before most of America signs on for work. Still, the outage comes at a tumultuous time for the company. Anthropic made headlines last week when President Trump ordered all federal agencies to stop using its AI services, after Anthropic and the Department of Defense could not come to an agreement on how the U.S. military could use Claude in its endeavors. The Defense Department wanted unrestricted access to the AI, while Anthropic wanted safeguards in place. The two could not reconcile, but not only did the Defense Department drop Anthropic, Defense Secretary Pete Hegseth declared the company a "supply-chain risk to national security." As such, no company that works with the U.S. military can also work with Anthropic. To be clear, none of that is likely related to this outage. But Anthropic likely has more users than ever experiencing this downtime, as the drama skyrocketed Claude to the top of Apple's App Store.

Claude is down: What we know about the outage
Claude, Anthropic's AI chatbot, is currently down, with the company confirming "elevated errors" on Monday. At 11:49 a.m. GMT (6:49 a.m. ET), Anthropic posted on its Claude status page that it was "currently investigating this issue," with an update approximately 30 minutes later. "We have identified that the Claude API is working as intended," the latest update reads. "The issues we are seeing are related to Claude.ai and with the login/logout paths." Mashable has reached out to Anthropic for further information. The errors are affecting the Claude chatbot, Claude Console (the Claude developer platform, and Claude Code (the company's AI-powered coding assistant). The last time Claude saw "elevated errors" was on Saturday, Feb. 28, 2026, with issues found and resolved affecting Claude Opus 4.6, its latest generation LLM (large language model) The outage came hours after Claude dethroned competitor OpenAI's ChatGPT in Apple's App Store, hitting number one as the most-downloaded free app in the U.S. (ChatGPT is second, Google's Gemini is fourth). The chart win came notably after President Donald Trump announced that the U.S. government would no longer use Anthropic tech including Claude, after which OpenAI entered into a deal with the U.S. Department of War to provide its AI technology for military use in "classified environments".

Is Claude down? Anthropic confirms major outage
Anthropic's Claude AI is currently experiencing a significant global outage today, Monday, March 2, 2026. Users attempting to access the chatbot are encountering a variety of errors, ranging from login failures to total service blackouts. The disruption comes at a high-profile moment for the company, following a recent surge in popularity that saw Claude reach the number one spot on the Apple App Store. The service disruption began to spike early in the morning, with Downdetector data showing a massive surge in user-submitted reports starting around 12:00 PM UTC. Reports peaked with nearly 2,000 active complaints within a short window, with the majority of users (42%) citing issues with the web-based chat interface. Another 34% of users reported problems with the mobile app, while others noted they were completely unable to log in to their accounts. Many users are seeing the message: "Claude will return soon. Claude is currently experiencing a temporary service disruption." Anthropic has been transparent about the ongoing investigation via its official status page. The company first flagged the issue at 11:49 UTC, noting "Elevated errors on claude.ai, console, and claude code." Below is the official timeline of events: While the main chatbot interface at claude.ai is currently unreliable, the outage is considered a "partial" disruption. Anthropic has confirmed that the Claude API (api.anthropic.com) is working as intended. This means that developers using Claude through third-party integrations or their own custom software should not be seeing the same level of errors as web users. However, the Claude Console and the developer-focused Claude Code tool are both suffering from elevated errors, impacting professional workflows and coding projects. The technical cause of the outage appears to be rooted in the login and authentication infrastructure rather than the AI models themselves. This explains why users who are already logged in might see "Internal Server Errors" (HTTP 500 or 529), while those trying to start new sessions are blocked entirely. This incident follows a minor disruption on February 28, where some users reported errors with the Claude Opus 4.6 model, suggesting a period of high infrastructure strain as Anthropic scales to meet its growing user base. If you are wondering "is Claude down" in your specific region, you can monitor the following resources for real-time updates: Anthropic's engineering team is currently implementing a fix, though no specific "Estimated Time of Recovery" (ETR) has been provided. Users are advised to wait for the status page to show a green "Operational" checkmark before attempting to re-authenticate or process complex prompts.

Anthropic restores Claude service after outage affecting thousands
Tech company Anthropic restored service to its artificial intelligence (AI) chatbot Claude after a nearly three-hour outage Monday that affected thousands, the company said in a statement. "Claude is back up and running across claude.ai and our apps. We're grateful to our users as the team works to match the incredible demand we've seen for Claude in recent days," Anthropic said in a statement to The Hill late Monday morning. According to a website monitoring the status of Claude from Anthropic, multiple Claude products faced partial outages for up to 2 hours and 45 minutes. Shortly after 6:30 a.m. EST, 2,133 people had reported problems with Claude to the website Downdetector, which tracks reported issues with different technology services. Last week, Defense Secretary Pete Hegseth said the Pentagon was labeling Anthropic as a supply chain risk. Hegseth's comments followed President Trump ordering federal agencies to stop using technology from Anthropic. "Effective immediately, no contractor, supplier, or partner that does business with the United States military may conduct any commercial activity with Anthropic," Hegseth said in a post on social platform X. Earlier in the week, the Pentagon warned of using the Defense Production Act against the tech company during tension over Anthropic's limits on its AI tools. On Tuesday, the Pentagon advised Anthropic that it could invoke the DPA to use the company's tools as it wanted.

Anthropic Investigates as Claude Suffers International Outage | PYMNTS.com
By completing this form, you agree to receive marketing communications from PYMNTS and to the sharing of your information with our sponsor, if applicable, in accordance with our Privacy Policy and Terms and Conditions. The artificial intelligence (AI) startup said Monday (March 2) that it was looking into what it called "elevated errors" on Claude. "We have identified that the Claude API is working as intended. The issues we are seeing are related to Claude.ai and with the login/logout paths," Anthropic wrote on its status page. A report on the issue from the website Bleeping Computer characterized the outage as affecting users in multiple regions and on multiple platforms. The outage is happening as Anthropic is both involved in a dispute with the U.S. military, and reportedly assisting in combat operations against Iran. The White House last week said that Anthropic would be cut off from its government contracts within six months, labeling the company a supply chain risk. "I am directing every federal agency in the United States government to immediately cease all use of Anthropic's technology. We don't need it, we don't want it and will not do business with them again!" President Donald Trump said in a post on Truth Social. The clash stems from a disagreement over how the military employs Claude, with Anthropic saying it could not allow the model to be used for mass surveillance operations within the U.S, or for autonomous weapons. After Trump's announcement Friday, Anthropic responded by saying it would challenge the government's actions in court. "No amount of intimidation or punishment from the Department of War will change our position on mass domestic surveillance or fully autonomous weapons. We will challenge any supply chain risk designation in court," the company wrote on its blog, adding that Defense Secretary Pete Hegseth had no authority to issue the supply chain risk designation. "Legally, a supply chain risk designation ... can only extend to the use of Claude as part of Department of War contracts -- it cannot affect how contractors use Claude to serve other customers," Anthropic added. Meanwhile, reports from both Reuters and The Wall Street Journal said the military had used Anthropic's technology, Claude included, in its attack. Sources told the Journal that U.S. Central Command uses Claude for intelligence assessments, identifying targets and to create simulations of battle scenarios.
