Resolved
On Wednesday, September 23, 2026, from approximately 08:15 to 11:18 (UTC), some customers experienced slowness and failed form submissions in UK instances of Secure Webforms.
This issue was caused by database performance limits in the UK production environment following a recent change. A database setting also caused some queries to run inefficiently. As a result, response times increased and some form submissions failed. To resolve this issue, our team temporarily paused a background synchronization task to reduce load, adjusted the database settings to improve query efficiency, and increased storage throughput. Secure Webforms returned to normal performance by 11:18 (UTC).
To prevent this type of issue in the future, we’re adding additional monitoring for database bandwidth. We’re also improving the efficiency of the background synchronization task.
No data loss occurred as a result of this issue.
