Anthropic’s Claude AI Back Online After 90-Minute Global Outage

HomeTech News Anthropic’s Claude AI Back Online After 90-Minute Global Outage By Guru Baran June 22, 2026 Anthropic’s Claude AI platform suffered a significant service disruption on June 22, 2026, affecting multiple flagship models and leaving developers worldwide scrambling for nearly 90 minutes before engineers restored full functionality. The incident began at 00:37 UTC on June 22, when Anthropic’s engineering team opened an investigation into elevated error rates impacting several Claude models simultaneously. The disruption hit five models in total Opus 4.8, Opus 4.7, Opus 4.6, Sonnet 4.6, and Haiku 4.5, marking one of the broadest multi-model outages the platform has seen this month. Affected services spanned the full Claude ecosystem, including Claude.ai chat interfaces, the Claude API (api.anthropic.com), Claude Code, and Claude Cowork. Developers relying on API integrations reported failed requests, while Claude Code users, a growing segment of enterprise engineering teams, experienced cascading workflow interruptions. Anthropic identified the root cause by 01:11 UTC and immediately began rolling out a targeted fix. Rather than a simultaneous restoration, recovery proceeded model by model in a staged rollout: 01:16 UTC — Opus 4.8 recovered 01:33 UTC — Haiku 4.5 recovered 01:56 UTC — Opus 4.7 recovered 02:01 UTC — Fix implemented; monitoring phase initiated 02:06 UTC — Full resolution declared The outage quickly drew developer frustration across social platforms, with Downdetector logging visible spikes in user-submitted reports focused on chat failures and Claude Code disruptions. For teams with production pipelines and deadline-sensitive workflows, even a sub-two-hour window of elevated errors can trigger significant downstream impact, particularly as Claude integrations deepen across software development and enterprise automation stacks. This incident is notably the third service disruption affecting Claude this month. Prior outages were recorded on June 2, a major disruption lasting several hours that impacted Opus 4.6, the Claude API, and Claude Code, and June 5, when networking performance degradation within Anthropic’s cloud infrastructure triggered elevated error rates across models. Despite the recurring incidents, Anthropic’s 90-day uptime figure remains above 98%, suggesting these are isolated spikes rather than systemic infrastructure failures. However, the frequency of disruptions in June alone raises questions about capacity planning as demand for Claude’s most powerful models continues to accelerate. As of 02:06 UTC on June 22, Anthropic’s official status page confirms all components, including the Claude API, Claude Code, Claude Cowork, and Claude for Government, are fully operational. Anthropic stated the team remains in active monitoring mode to ensure stability holds following the staged recovery. Follow us on Google News, LinkedIn, and X to Get More Instant Updates.
