This one was egregious: after a one hour user pause, apparently they cleared the cache and then continued to apply “forgetting” for the rest of the session after the resume!
Seems like a very basic software engineering error that would be caught by normal unit testing.
To take the opposite side, this is the quality of software you get atm when your org is all in on vibe coding everything.
You can argue they're lying, but I think this is just folks misunderstanding what Anthropic is saying.
They're not gaslighting anyone here: they're very clear that the model itself, as in Opus 4.7, was not degraded in any way (i.e. if you take them at their word, they do not drop to lower quantisations of Claude during peak load).
However, the infrastructure around it - Claude Code, etc - is very much subject to change, and I agree that they should manage these changes better and ensure that they are well-communicated.
Sure they didn't change the GPUs their running, or the quantization, but if valuable information is removed leading to models performing worse, performance was degraded.
In the same way uptime doesn't care about the incident cause... if you're down you're down no one cares that it was 'technically DNS'.
