Webhook delivery delays from GitHub led to a backlog of workflows being triggered all at once as delivery resumes. This caused a temporary spike in demand for some Semaphore machines. We are actively working to reduce the impact and restore normal capacity. We continue monitoring both GitHub’s incident and Semaphore infrastructure closely, and we will provide further updates as conditions stabilize.
