Incident with GraphQL API Requests
Summary
On August 11, 2026, between 14:00 UTC and 16:00 UTC the GraphQL API service was degraded and customers in saw higher than normal timeouts. On average, the timeout rate was 0.06% and peaked at 0.14% of requests routing to the service. <br /><br />This was due to increased utilization at one of our sites which caused resource contention across our dependencies, leading to an increase in timeouts for GraphQL requests. We mitigated the incident by increasing capacity to alleviate the capacity bottl
