Post-incident report

Published (Nov 19, 2025)

On November 18, 2025, a subset of event sites running on our managed hosting provider’s legacy network experienced an issue in which automated cron jobs stopped executing. This disrupted registration flows on the affected sites, producing intermittent errors for attendees attempting normally functioning activities such as completing registration or payment. The longest sustained window lasted approximately 1 hour 36 minutes.

Sites on the Cloudflare Advanced Network were not affected. Only sites still running on the provider’s legacy network were impacted. Session playback, channels, and other attendee-facing surfaces continued to operate normally throughout.

No data loss was detected. Backup registration capture kept all submitted attendee records intact and they were reconciled into the primary registration system once service was restored.
