Anthropic’s Claude AI services are down, and thousands of users are feeling the pain. More than 10,000 users began reporting issues shortly after 9 a.m. ET on Tuesday, according to Downdetector.
The outage hit multiple fronts at once. Elevated errors were confirmed on Claude.ai, Claude Code, Claude Cowork, and Claude’s API, according to Anthropic’s status page. That means the core conversational service, the coding assistant, the collaborative workspace, and the underlying programming interface all showed signs of trouble.
What Users Are Seeing
The failure message is blunt: “account temporarily unable to authenticate.” Users attempting to access the services “may see failed requests, errors loading or sending conversations, or be asked to sign in again,” according to Anthropic. The company adds that retrying may succeed, though it does not guarantee a fix on the first attempt.
That is a common pattern in cloud outages. Services can become unstable without fully crashing, and authentication checks can fail while the underlying system is still running. Anthropic’s note that retrying may work suggests the problem is transient, not permanent — but with more than 10,000 users affected, the window of frustration is wide.
The Scale of the Outage
The 10,000-plus figure comes from Downdetector, which tracks reports of service disruption across the web. The timing — a sudden spike shortly after 9 a.m. ET — suggests a shared trigger rather than a slow build. Something happened at that hour that pushed a large group of users into the same failure state.
For users who rely on Claude for daily work — coding, collaboration, conversation — the morning rush was interrupted by a system that could not answer.
What Anthropic Has Said
Anthropic has acknowledged the issue through its status page. The company has not yet provided a timeline for resolution beyond noting that retrying may succeed. That is a standard response, but it does not address the underlying cause.
The company has also posted messages on its status page confirming the elevated errors across all four affected services. The API is a particular concern, since it underpins how other software connects to Claude. If the API is down, third-party tools built on top of Claude lose their connection point.
“Users attempting to use the services ‘may see failed requests, errors loading or sending conversations, or be asked to sign in again,’ according to Anthropic.”
What Comes Next
For individual users, the advice is simple: wait and try again. Anthropic’s note that retrying may succeed means the system may be working for some people even as it fails for others. That is a frustrating position to be in, especially for those whose work depends on Claude being available now.
Outages are not new to AI services, but they do raise a practical question about reliability. AI tools are becoming essential to daily work for developers, writers, and researchers. When one goes down, the impact is immediate.
The failure affects anyone who relies on Claude for:
- Coding through Claude Code
- Collaboration through Claude Cowork
- Conversation through Claude.ai
- Integration through Claude’s API
Anthropic’s status page confirms the elevated errors across all four affected services. That is a broad failure, and it affects anyone who relies on Claude for coding, collaboration, or conversation.
The company’s note that retrying may succeed is a useful tip, but it is not a solution. It tells users what to do next — try again — without explaining why the failure happened in the first place.
Anthropic’s Claude services are down, and users are waiting. The company has acknowledged the issue, noted that retrying may work, and left it at that. For now, the advice is simple: sit tight, try again, and hope the system comes back soon.
The outage is a reminder that even the most advanced AI systems depend on reliable infrastructure. Authentication failures may seem small, but they ripple outward fast when thousands of people share the same problem at the same hour.
