01 What happened

On the AE→AE corridor over 2026-05-05 to 06-03, the daily inviteToRing raw average rose from 1.72 in early May to 23.09 by 06-03. Over the same window the <36000 s filtered average moved only 1.72 → 2.74, and p50/p95 stayed flat at 1 / 6.

The daily inviteDelay <36000 s filtered average held at ~270–340 s through most of the window and rose to a single-day high of 438.7 s on 2026-05-27. inviteDelay p95 was ~590–1,050 s in the first half and was elevated across 05/23–05/29, peaking at 1,892.6 s on 2026-05-27. p50 stayed at ~1.1 s; the unfiltered raw average ranged 1,200–21,000 s.

avg (raw) avg (<36000 s)

Raw average climbs to 23.09 by 06/03; the <36000 s filtered average stays at ~1.7–2.7. The gap between the two lines is the share of values at or above 36000 s.
