Claude users hit a login outage on Friday, 13 November. Anthropic’s status page lists the incident as “Elevated errors on claude.ai, Claude Code, and platform.claude.com” and now marks it resolved.
What Anthropic’s status page says
The first entry reads: “We are investigating an issue with users authenticating to Claude.ai and Claude Code.” It was posted at 09:58 UTC, which is 3:28 PM IST. A fix was deployed and monitoring began at 11:05 UTC (4:35 PM IST). At 11:58 UTC (5:28 PM IST), Anthropic wrote that the issue affecting claude.ai and Claude Cowork “has been resolved.” The incident touched claude.ai, the Claude Console, Claude Code and Claude Cowork, according to the Claude status page.
What Downdetector shows
A post from Downdetector said user reports indicated problems with Claude AI starting around 4:51 AM Eastern, which is 3:21 PM IST. Downdetector collects reports from users, so it is a signal of user experience and not a confirmation of cause or scale. We did not independently verify the current number of reports.
What is still unclear
At 6:25 PM IST the main status page still listed claude.ai as “Major Outage” in its component list, while the incident entry above said resolved. We cannot tell from that banner alone whether the problem has returned or is widespread, so the all-clear is Anthropic’s own and we are treating it that way.
A separate Microsoft 365 issue
A different incident is open. Anthropic says its Microsoft 365 connector is failing for most mail, calendar and search requests because of a Microsoft service problem, and Claude for Outlook is affected. That is not the login issue. We covered the Microsoft side in our report on the Outlook outage and Exchange Online access problems.
What to do
If Claude shows a reconnect prompt, copy any unsent text before you reconnect. If it still says it is unavailable, check the status page again for updates.
This is a developing story and we will update it if Anthropic changes its status.
