Published (Apr 22, 2026)
At 8:34 PM UTC on April 21, 2026, we were notified of a critical outage affecting event sites hosted in our Google Cloud us-central1 (Iowa) region. Our on-call team immediately engaged senior engineering, who remoted into the origin infrastructure, rebooted the affected server, and restored accessibility to event sites.
The primary outage window lasted 40 minutes. Shorter recurrences were observed in the following hours as origin capacity re-balanced, and were resolved without further intervention. Registration, channels, and Zoom integration continued to function on healthy routes throughout.
This was classified as a tier-3 incident. Mitigations were deployed on affected sites to minimize service disruption during the recovery window.
As this is one of the longest and broadest service disruptions in Jumbo’s history, we are reviewing our backup and failover planning to ensure faster recovery for future events of this nature.
