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?

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.
