Final update
A recent rollout caused the AuthZ (RBAC) service to perform many redundant folder-tree fetches for each authorization check. For a small number of tenants in the prod-us-east-0 and prod-eu-west-2 regions with very large folder trees. This added a few milliseconds to every check, which increased request latency. The approximate timeframe of the impact is: 2026-02-26 17:24:43 UTC to 2026-02-27 14:33:53 UTC. This has now been resolved.
