Increase in latency in DeviceCheck attestationData endpoint

Hello,

Since the 21st of March 2024 around 6PM UTC I've been observing a very significant an increase (more than quadrupled) in P99 and P95 latency on https://data.appattest.apple.com/v1/attestationData

I'm calling other endpoints of the same API, and I'm not observing a similar increase there.

I tried submitting a report in Feedback Assistant but it's not working for me at the moment.
