Anthropic faced a widespread Claude AI outage on September 22, 2026, disrupting access across multiple regions. Users reported problems with Claude and Claude Code as Downdetector logged more than 1,600 reports. The disruption affected Anthropic’s AI services during a period of repeated technical incidents.
The latest Claude AI outage affected users across different locations, with login and service access problems. Reports also indicated issues with Claude Code, which developers use for coding and software workflows. Anthropic did not disclose a confirmed technical cause for this specific incident.
Anthropic’s status information now shows its services operating normally after the disruption. Claude.ai, Claude Code, the API, Console, and other listed services are currently operational.
The outage also adds another disruption to Anthropic’s recent service history. Earlier incidents affected different Claude models and services during August and September.
A separate incident on September 3 affected several models, including Claude Mythos 5.1, Fable 5.1, and Opus 5. Anthropic later said it identified the cause and worked on restoring service.
The timing also follows Anthropic’s September 1 launch of Claude Fable 5.1 and Claude Mythos 5.1. Anthropic described the models as its most advanced systems for coding and knowledge work.
For developers, interruptions can disrupt coding sessions, automated workflows, and applications using Anthropic’s API. Claude Code disruptions can also interrupt development tasks already running through the service.
The latest incident highlights how dependent digital workflows have become on cloud-based AI platforms. Short service interruptions can quickly affect both individual users and developer operations.
Anyone still facing errors can check Anthropic’s status page before changing local settings. Restarting the app, refreshing the browser, or switching networks can help identify isolated connection problems.
