April 8 was a rough morning for anyone running Claude-dependent workflows. Anthropic's chatbot and API went down, with users reporting errors across claude.ai and third-party apps built on the API. Both consumer accounts and business API integrations were affected.
Anthropic’s status page confirmed the outage. The incident appeared to last several hours before service was restored, though no post-mortem or root cause analysis has been published.
Outages at major AI providers have become a regular occurrence as usage grows faster than infrastructure can scale. OpenAI, Google, and Anthropic have all had significant downtime events in the past year. For most users, an occasional outage is a manageable inconvenience. For developers running production applications that route user requests through Claude's API, each outage is a direct argument for building fallback routing to a backup model - a safety net most teams haven't built because it adds engineering complexity and outages have been infrequent enough to feel like edge cases.
The April 8 incident is a reminder that AI APIs, however reliable they've become, are still external dependencies. If Claude being unavailable for a few hours breaks your product, that's a risk worth addressing in your architecture before the next outage, not after.
