This coincides with Anthropic's peak-hour announcement (March 26th). Could the throttling be partly a response to infrastructure load that was itself inflated by the TTL regression?
It would be too fucking funny if this were the case. They're vibe coding their infrastructure and they vibe coded their response to the increased load.
You'd think they would have dashboards for all of this stuff, to easily notice any change in metrics and be able to track down which release was responsible for it.
They probably do, then they pipe it into a bunch of Claude subagents and then you get the current mess.
