  6. Resolved

    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 bottleneck. <br /><br />We are working to improve our monitoring so that we can proactively reduce the impact of high consumption requests in addition to scaling up; Additionally, we will improve our time to detection and mitigation of issues like this one in the future.
