This of course could be a coincidence. But I suppose also that if one goes down the others get slammed, so there could be a cascade. If I were another provider I would possibly monitor Claude outages (or vice versa) as a load predictor.
Quite possibly, yeah! Although in the past, whenever Anthropic has been down, I've always been able to rely on using OpenAI.
Possibly people switching work from Claude to Codex?
