Claude API experienced elevated error rates across multiple models on February 25, 2026
Claude's status page reported elevated error rates affecting multiple models through their API endpoint at api.anthropic.com. The incident was tracked and resolved within approximately 31 minutes.
Timeline and Resolution
The incident followed this sequence:
- 17:15 UTC: Investigation began with initial status update
- 17:21 UTC: First update confirming continued investigation
- 17:21 UTC: Second identical update (likely system duplicate)
- 17:46 UTC: Incident marked as resolved
The status page indicates this was a specific incident affecting the Claude API service, not a general outage of all Anthropic services. The resolution came relatively quickly after detection.
Technical Context
When AI model APIs experience elevated error rates, this typically manifests as increased 5xx HTTP status codes, timeouts, or degraded response quality. For developers using Claude in automated workflows, such incidents can trigger retry logic, fallback mechanisms, or require temporary suspension of AI-dependent features.
The status page provides subscription options for incident notifications via email or SMS across international phone numbers, though the actual incident reporting was minimal on details about root cause or specific affected models.
