Public problem
Tail latency tells a different story from the average

Separate expected client errors from server failures. A deliberately rejected invalid request should not make the service look unavailable, although a sudden increase can still reveal a client integration problem.

Show the observation window beside the number. Comparing a five-minute percentile with a daily average is easy to do accidentally when dashboard labels are too compact.
