Live updates. Status as of 13 November 2026, 10:45 UTC: the outage is ongoing. Anthropic’s status page shows “Partial System Outage”, claude.ai is in major outage, Claude Code and the Console in partial outage. The API is working normally. I check the status every few minutes and add changes at the bottom of this article.
In short: On 13 November 2026, starting at 09:58 UTC, Claude is having an outage. Anthropic reports a problem with users logging in to claude.ai and Claude Code. Mostly the claude.ai website and apps are down, Claude Code and the platform.claude.com console are partially down, and Cowork is degraded. The Claude API (api.anthropic.com) and Claude on AWS, Google Cloud and Microsoft Foundry are working normally according to the status page.
If you can’t log in to Claude this morning or the chat keeps throwing errors, it is not your account or your browser. At 09:58 UTC Anthropic opened an incident on its status page called “Elevated errors on claude.ai, Claude Code, and platform.claude.com”. Below is what the official status page says and what you can do until the service is back.

What Anthropic says
So far there is one message, posted at 09:58 UTC: the company is investigating an issue with users authenticating to claude.ai and Claude Code and will provide an update “as soon as possible”. The incident status is “investigating”, which means the cause is not known yet and there is no estimated time for a fix.
A second, separate incident has been open since yesterday: since 12 November at 17:52 UTC most requests through the Microsoft 365 connector (mail, calendar, search) have been failing, and the Claude for Outlook add-in is affected too. Anthropic says the cause is a Microsoft 365 service incident. The last update on it was posted on 12 November at 22:23 UTC. It is not the same problem as today’s login issue.
What to do right now
- Don’t clear cookies or force a logout. Since the problem is with logging in, logging in again may fail right now. If you still have a Claude tab open, just try refreshing it in a few minutes.
- Have an API key? Use it. The API is working normally according to the status page. Claude Code can run on an API key (the
ANTHROPIC_API_KEYenvironment variable) instead of a Pro or Max account login. You then pay per token at API prices, and you may not be able to create a new key right now because the Console is also affected. - Your company uses Claude in the cloud? Claude on AWS, Google Cloud and Microsoft Foundry is working without disruption according to the status page.
- Outage or usage limit? A message that you have hit your message limit is not an outage. It shows up even when every service is green.
- Follow the official status. status.claude.com shows the state of every service and lets you subscribe to email notifications.
Does this happen often
Anthropic’s status page lists 15 incidents between 14 October and today, including the two that are still open. Most of them affected single models or connectors and lasted less than two hours. The last time claude.ai, Claude Code, Cowork and the API went down together was on 29 September (from 14:21 to 16:27 UTC). The last login problems on claude.ai were reported on 24 August, when two short issues lasted from a few minutes to about a quarter of an hour.
