We have deployed a fix for the issue causing some users to experience intermittent failures when accessing the Webhooks API and configuration pages. We are monitoring to confirm full recovery.

- investigating
The previous mitigation did not resolve the issue. We are investigating further. The affected endpoint is the webhook deliveries API (https://docs.github.com/en/rest/repos/webhooks?apiVersion=2022-11-28#list-deliveries-for-a-repository-webhook) and its organization and integration variants. Overall impact remains low, with under 1% of requests failing for a subset of customers.

- resolved
On March 6, 2026, between 16:16 UTC and 23:28 UTC the Webhooks service was degraded and some users experienced intermittent errors when accessing webhook delivery histories, retrying webhook deliveries, and listing webhooks via the UI and API. On average, the error rate was 0.57% and peaked at approximately 2.73% of requests to the service. This was due to unhealthy infrastructure affecting a portion of webhook API traffic. We mitigated the incident by redeploying affected services, after which service health returned to normal. We are working to improve detection of unhealthy infrastructure and strengthen service safeguards to reduce time to detection and mitigation of issues like this one in the future.
