Anthropic confirms outage

As complaints mounted online, Claude developer Anthropic acknowledged the issue and confirmed that its teams were investigating.

The company listed an incident titled “Elevated errors across multiple models” on its status page and said it was working to resolve the problem.

The incident was first reported at 06:04 UTC on 2 June. Anthropic later updated the status to “Identified” at 06:39 UTC, stating that the root cause had been found and that a fix was being implemented.

The company’s status dashboard showed several services experiencing a partial outage, including Claude.ai, Claude Console (platform.claude.com), Claude API (api.anthropic.com), and Claude Code.

Social media reactions to the outage

Following the outage, users turned to social media to share screenshots of failed prompts, loading screens, and error messages.

One user wrote, “Free users of Claude hitting walls again — rate limits, queues, and ‘try again in 5 hours.’ That’s exactly why Premium feels premium. More messages, priority access, no frustration. Worth every rupee when you actually rely on it daily.”

Another user shared a meme suggesting that Claude users would switch to ChatGPT during the outage.

A third wrote, “Claude is down again; 92% vibe developers have to use their braincells to code,” highlighting the increasing dependence on AI platforms to continue with normal and professional work.

Anthropic’s AI products report performance issues

Tuesday’s disruption follows a series of incidents reported on Anthropic’s status page in recent days, including elevated error rates affecting Claude Opus, Sonnet, and Haiku models.

In recent months, some users have also raised concerns about context handling, agent performance, and system strain during periods of high demand. Anthropic has previously acknowledged the challenges involved in scaling advanced AI systems and services.

At the time of publication, Anthropic’s status page indicated that a fix had been implemented and that the company was monitoring systems to ensure service stability.
