Single nine reliability would be 90% uptime lol. For 99.9% we call it triple 9 reliability.

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.
