Is Claude down? Anthropic confirms ‘elevated errors’ as thousands report outage
Claude outage sparks global user complaints
Anthropic’s AI chatbot Claude is experiencing widespread service disruptions, leaving thousands of users unable to access the platform. The company confirmed “elevated errors” on Monday, triggering a surge in searches for “Is Claude down?” and “Claude outage today.”
The disruption comes at a pivotal moment for Anthropic, whose flagship chatbot Claude recently climbed to the top of Apple’s US App Store rankings, overtaking rivals in the competitive AI space.
Here’s what we know so far.
Anthropic Confirms “Elevated Errors” on Claude.ai
At 11:49 a.m. GMT, Anthropic posted an update on its status page confirming it was investigating issues affecting Claude. Roughly 30 minutes later, the company clarified that the Claude API remained operational, but users accessing Claude via its web interface were experiencing problems.
“We have identified that the Claude API is working as intended,” Anthropic wrote. “The issues we are seeing are related to Claude.ai and with the login/logout paths.”
This means developers integrating Claude into third-party apps were largely unaffected, while direct users of Claude.ai, Claude Console, and Claude Code faced interruptions.
Thousands Report Claude Not Working
According to monitoring site Downdetector, more than 2,000 users reported issues during the peak of the outage.
Users attempting to log in were met with error messages describing a “temporary service disruption.” Screenshots circulating on social media showed failed login attempts and inaccessible dashboards.
The outage appears to primarily impact:
- Claude.ai (web interface)
- Claude Console (developer platform)
- Claude Code (AI-powered coding assistant)
Anthropic has not yet provided a detailed explanation for the root cause.

Is Claude API Down?
One of the most pressing questions from developers has been whether Claude’s API is affected.
Anthropic confirmed that the Claude API is functioning normally. This suggests that backend systems and integrated applications using Claude’s AI models remain operational, isolating the issue to login pathways and user authentication systems.
This distinction is significant for enterprise users who rely on Claude-powered integrations within productivity tools and apps.
Timing Raises Questions Amid Pentagon Dispute
The outage comes during heightened public attention on Anthropic due to its standoff with the US Department of Defense.
Recently, President Donald Trump announced that federal agencies would stop using Anthropic’s technology. The company has reportedly resisted providing unrestricted AI access for certain military applications, citing ethical concerns.
Shortly after that announcement, OpenAI, maker of ChatGPT, confirmed a defense-related AI agreement.
Despite the political controversy, Claude had surged in popularity, reaching the number one position on Apple’s App Store in the United States before the outage occurred.
There is no evidence linking the outage to geopolitical tensions, and Anthropic has not suggested any external interference.
Previous Claude Outages
This is not the first time Claude has experienced “elevated errors.” Just days earlier, on February 28, issues were reported affecting Claude Opus 4.6, the company’s latest large language model. That disruption was later resolved.
Repeated outages, however, raise concerns about infrastructure resilience as AI platforms scale rapidly to accommodate millions of users.
Why Is Claude Down?
As of now, Anthropic has not disclosed the technical cause of the outage. Based on its statement, the issue appears limited to authentication systems rather than core AI functionality.
Outages in high-traffic AI systems can result from:
- Server overload due to user surges
- Authentication server failures
- Deployment bugs during updates
- Cloud infrastructure disruptions
Anthropic says it is actively investigating and will provide further updates.
What Users Should Do
Users unable to access Claude are advised to:
- Check Anthropic’s official status page
- Refresh sessions after logging out
- Monitor Downdetector for real-time reports
There is no indication that user data has been compromised.
The Bigger Picture for AI Platforms
The Claude outage highlights the fragility of today’s AI-driven internet ecosystem. As generative AI tools become deeply embedded in workflows, from coding to content creation, even brief disruptions can have outsized ripple effects.
With competition intensifying between Anthropic, OpenAI, and Google’s Gemini, uptime reliability is becoming as critical as model performance.
For now, thousands of users are waiting for services to be fully restored.
