  1. resolved Apr 23, 2026, 08:22 PM UTC

    Between 06:07 and 06:57 UTC, during a routine OS upgrade to our search infrastructure, a pre-existing corruption on one of our coordinator nodes in a single availability zone caused it to stop serving requests. As a result, search query requests routed to that availability zone were dropped, affecting approximately 142,000 requests over the course of the incident. The issue was resolved by provisioning additional coordinator nodes in the availability zone to restore capacity, after which the corrupted node was decommissioned.
