Between 16:40 and 17:36 UTC, Mux experienced elevated webhook delivery latency affecting Mux Video VOD and Live, with delays averaging ~5 minutes and peaking up to 15 minutes. The root cause was an issue in an internal database cluster that disrupted the webhook event queuing pipeline; video processing, playback, and API requests remained unaffected and no events were lost. The database issue was resolved by 17:36 UTC, all delayed webhooks were delivered, and delivery times stabilized within the 48-minute incident window.
