Anthropic Claude AI service outages and safety research

Overview

Anthropic has experienced recurring service disruptions affecting its Claude AI ecosystem. Following previous outages in August, a new global outage occurred on 24 August. Beginning around 05:06 UTC, the disruption caused high error rates across several models, including Claude Mythos 5, Claude Fable 5, and Claude Opus 5. The incident impacted the web interface, Claude API, Claude Code, and Claude Cowork, with users reporting error 529 and infinite loading screens. Anthropic confirmed the incident on its status page, noting “elevated errors on requests to Claude Mythos 5, Claude Fable 5, Claude Opus 5, and Claude Opus 4.8.” While reports on Downdetector indicated a spike in connectivity issues, Anthropic stated that error rates began to stabilize on certain models, such as Opus 5 and Fable 5, as engineers worked toward a full resolution. The company has not yet released a specific cause for the outage. On 3 September 2026, a broader wave of technical difficulties impacted the AI sector. Anthropic confirmed a partial outage affecting various Opus and Mythos/Fable models, specifically mentioning elevated error rates for Claude Mythos 5.1, Claude Fable 5.1, and Claude Opus 5. This disruption coincided with significant service disruptions at OpenAI, where a routing error affected ChatGPT and Codex, and at xAI, where Grok disruptions were attributed to an outage at a Memphis compute center. Subsequent investigations identified a failure at a SpaceXAI data center in Memphis, Tennessee, as the cause for the Grok outage. Because SpaceXAI provides compute capacity to external partners, including Anthropic, the failure likely impacted other services. Elon Musk stated that corrective measures are being implemented to prevent similar occurrences in the future. On 29 September 2026, Anthropic faced another major service outage beginning around 10:00 a.m. ET.
