Single 9 would be 90%, which is roughly what I’m experiencing between CC for Web and the Claude iOS app. About 1 in 10 messages fail because of an unknown error and 1 in 10 CC for web sessions die irrecoverably. It’d probably be worse except for the fact that CC’s bugs in the terminal aren’t show stoppers like they are on web/mobile.

The only way Anthropic has two or three nines is in read only mode, but that’s be like measuring AWS using the console uptime while ignoring the actual control plane.

Single nine could be just 9% :D
