Claude Code was down, forcing developers to take a long coffee break
TL;DR
Anthropic's Claude models experienced a major outage today – Claude Code showed 500 errors, all APIs were affected Anthropic identified the root cause and deployed a fix within roughly 20 minutes Claude Opus 4.5 had errors yesterday; earlier this week there were also issues purchasing AI credits Developers relying on the tool were left waiting – an unusual spike in Claude outages in a short period.
Nauti's Take
20 minutes of downtime sounds like a quick fix, but for developers it feels like an eternity – especially when it's not the first issue this week. Anthropic has built a reputation for reliability; clusters like this chip away at it.
The dependency on cloud AI tools becomes very real here: no fallback, no local model, just wait. That's the deal you accept – but it shouldn't become a pattern.
