On May 25, 2026, between 09:02 UTC and 09:11 UTC, Git push operations over HTTPS and SSH experienced elevated failures. During this window, an average of 31% and a peak of 43% of push requests failed.
The incident was caused by a recently enabled code path that issued an unexpectedly expensive database query against a primary database. The resulting load exhausted the database's connection pool, which caused the push failures above. The acute impact resolved automatically as in-flight work completed.
We mitigated the incident by disabling the feature flag controlling the new code path.
We are working to route the affected read to a replica to reduce the likelihood of issues like this in the future.

Between June 1, 2026, 23:00 UTC and June 4, 2026 04:11 UTC, customers experienced delays in Dependabot scheduled version updates. Pull request creation for version updates was delayed, with delays increasing over time and reaching up to two days. Approximately 1.5 million repositories with active Dependabot version update configurations were affected. Dependabot security updates were not affected. The primary cause was changes to an internal platform service that routes requests for Dependabot and other services. We mitigated the incident by deploying a fix that enables batch enqueuing of update jobs, which significantly increased processing throughput. Once the backlog was drained, Dependabot returned to normal processing times. To reduce the risk of recurrence, we are working on tuning batch size and concurrency limits for Dependabot update job processing. We are also adding monitoring for job processing lag to enable earlier detection and faster mitigation of similar issues.
On June 2, 2026, between 21:54 UTC and June 3, 2026 06:45 UTC, the Spark service was degraded and users were unable to store or retrieve data for their Spark apps in one of our hosting regions. Users could still make changes to their app configuration during this time. The error rate peaked at 25% of affected requests to the service. Impact was limited to users whose requests were served through a single affected region; 43 users experienced errors during this window.The root cause was a configuration that referenced a service component by a fixed address rather than a dynamic service endpoint. When the component was replaced, requests could no longer reach the fixed address and began to fail. We resolved the incident by updating the configuration to use a our standard service endpoints that are resilient to component replacement. Recovery time was extended because replacing the component required overrides to a temporary deployment safeguard.We are working to add validation that prevents fixed infrastructure addresses from being used in application configuration outside of test environments and to improve our monitoring to reduce our time to detect.
