On Thursday, August 22, 2024, from approximately 2:06 p.m. until 8:26 p.m. (UTC), some customers on the US instance of the KnowBe4 PhishER console experienced slow loading and login issues.

This incident was caused by an unusually high number of requests which reduced performance for one of our databases.

To resolve this issue, we modified our database configuration and reduced the number of simultaneous requests that can be made to the database.

This change allowed the backed-up queue of requests to be processed more quickly and the console returned to regular performance by 8:26 p.m. (UTC) on August 22, 2024.

To prevent this issue in the future, we have improved our testing processes and monitoring of request traffic by increasing visibility and automated alerts.

No data loss occurred as a result of this issue.
