API Error (503 no healthy upstream)
I checked the status of Claude Code and it seems up and running. I even used private VPN to check from different locations with the same result;

503is the universal errors for not being able to accept connections and i searched it up and it basicly just means the servers are overloaded
Thank you. But it seems it is not effecting everyone...

Hey folks, there was a broad GCP outage that impacted the Anthropic API and by extension Claude Code.
It is fully resolved now.
I’ve been having problems for days
