Recent service disruptions

The latest incident follows a series of service interruptions recorded by Anthropic in recent weeks. Previous disruptions affected major Claude models, including Opus, Sonnet and Haiku, leading to elevated error rates and temporary service degradation.

At the time of reporting, the company had not provided an estimated timeline for full restoration of services.
