Is Claude Down Right Now? — May 2026 Outage Explained

🟢 Update May 15, 2026 — This incident has been resolved.
Claude is fully operational. See full timeline below.

If Claude stopped working for you overnight, you weren't alone. Anthropic's Claude experienced elevated error rates across multiple models in the early hours of May 15, 2026 and it's part of a pattern that's been building throughout this month.

The incident has since been resolved. Here's the full timeline, what was affected, and what to check next time Claude goes quiet on you.

What Happened — The Full Timeline

The incident began just after midnight UTC on May 15, 2026:

00:18 UTC — Anthropic begins investigating reports of elevated error rates across Claude models.

00:19 UTC — First public update posted: investigating the issue.

01:06 UTC — Anthropic identifies the affected models: Claude Opus and Sonnet 4.6 are impacted. Opus 4.7 success rates return to normal at this point.

01:26 UTC — Anthropic confirms it is working to resolve errors on Opus 4.6 specifically, with Sonnet 4.6 and Opus 4.7 returning to normal.

01:46 UTC — Incident resolved. All models return to normal operation.

Total duration: approximately 88 minutes from first report to resolution.

What Was Affected

The outage hit Claude Opus 4.6 and Claude Sonnet 4.6 hardest. More than 2,000 users had reported problems with the platform, with most saying they had issues with Claude Code specifically.

User reports came in from South Africa, Germany, Bangladesh, the UK, and the Netherlands — with complaints ranging from Claude Code timing out on responses and chat history getting jumbled, to the service returning a flat "this isn't working right now" message.

Claude Opus 4.7 recovered first, before Anthropic had even identified the full scope of the issue, suggesting the problem was model-specific rather than a platform-wide infrastructure failure.

This Has Been a Rough Month for Claude

Last night's incident wasn't isolated. Looking at May 2026 alone: Claude was down for 4 hours and 15 minutes on May 7, experienced a warning period followed by 3 hours and 16 minutes of downtime on May 8, went down again for 28 minutes on May 9, had a 49-minute outage on May 12, and was down for 2 hours and 50 minutes on May 13 — just two days before last night's incident.

Over the last 90 days, Claude had 137 incidents — 46 major outages and 91 minor incidents — with a median duration of 1 hour and 6 minutes.

That's a significant reliability concern for teams and developers who depend on Claude through the API, Claude Code, or claude.ai for daily work.

status.claude.com — Anthropic's official status page. Updated during incidents, though sometimes with a short delay after problems begin.

statusgator.com/services/claude — Third-party monitoring that detects outages before they are officially acknowledged, with an average detection delay of 15 to 30 minutes ahead of official acknowledgment.

downdetector.com/status/claude — User-submitted reports give you a real-time crowd signal even before Anthropic posts anything.

X (Twitter) — Search "Claude down" for instant community reports. Usually the fastest signal of all.

What to Do When Claude Is Down

If you're mid-workflow and Claude goes offline, a few practical options:

Switch models if you have API access — if Opus is down, Sonnet or Haiku may still be operational as different models are often affected differently as seen in last night's incident.

Switch to an alternative temporarily — ChatGPT, Gemini, and Mistral are the most capable alternatives for most tasks.

For Claude Code users specifically — the VS Code extension sometimes stays partially functional even during API disruptions. Try restarting the session before giving up entirely.

If you're on a Pro or Team plan and hit a wall during a confirmed outage, Anthropic's support is at support.anthropic.com.

Why Is Claude Down So Often Lately

No official explanation has been given for the frequency of incidents in May 2026. The pattern — multiple outages per week across different model versions — suggests infrastructure under significant load pressure rather than isolated bugs.

Anthropic has been rapidly expanding Claude's capabilities and model lineup in 2026. Faster model releases and growing user demand are the most likely contributing factors, though without a post-mortem from Anthropic, that remains speculative.

It's worth noting that no major AI platform maintains perfect uptime at scale. OpenAI's ChatGPT and Google's Gemini have both had notable outage weeks in 2026. But the frequency of Claude incidents this month is above the norm even by those standards.

CONCLUSION

Last night's incident is resolved and Claude is back to full operation. But the broader pattern of outages throughout May 2026 is something developers and heavy users should take seriously when planning workflows that depend on Claude availability.

Bookmark status.claude.com, set up alerts on StatusGator if you rely on Claude for production work, and have a fallback model ready. The outages will keep happening — what matters is how fast you can adapt when they do.
