Anthropic’s Claude AI is showing signs of overload again.
On Monday morning, users trying to work with Claude encountered failed requests and a “529 Overloaded” error. The message says the problem is a temporary server-side issue, then sends users to Anthropic’s status page. A screenshot shared with TNW shows the error appearing in the Claude interface.
Anthropic’s own incident report is broader, and more cautious. At 05:06 UTC on 24 August, the company said it was investigating elevated errors affecting requests to Claude Mythos 5, Claude Fable 5, Claude Opus 5, and Claude Opus 4.8. The incident also affects claude.ai, the Claude API, Claude Code, and Claude Cowork.
At 05:27 UTC, Anthropic said it had identified the cause and was working on a fix. Its latest update, posted at 06:42 UTC, says the company is still working to resolve the issue. The status page does not yet provide a recovery time or a technical explanation.
The distinction matters. “529 Overloaded” describes what at least some users are seeing, but Anthropic has not said that overload is the root cause of the wider incident. For now, the public record establishes elevated errors across several models and products, not why they occurred.
