Between 12:51 and 13:38 UTC on September 7, 2026, the COR web application experienced degraded performance for approximately 47 minutes. Most users would have noticed slower page loads, and during part of this window a portion of requests failed and had to be retried — including a brief period of a few minutes when most requests did not complete. The cause was a configuration issue introduced by a recent infrastructure update. It was not related to capacity or traffic levels. Once identified, we shifted traffic to a healthy server and service returned to normal at 13:38 UTC. We have found no indication of data loss, and no customer action is required. We have corrected the configuration and are adding automated checks so this class of issue is caught before it reaches production. We apologize for the disruption.
