- This incident has been resolved. Thank you for your patience and understanding as we addressed this issue. A detailed root cause analysis will be shared as soon as it is available.
+ We identified that an advisory-publication driven fan-out was overwhelming Dependabot alert processing on repositories by saturating the queue with its own events, delaying processing of events related to repository pushes. We have now isolated this fan-out and applied a throttle so it runs at a fixed rate and cannot delay other events. This remediation has successfully prevented a new fan-out process impacting users.
