SurfProtect URL parsing Wednesday 6th December 2017 17:50:00

Some schools were affected by an issue that caused a crash on the SurfProtect decision backend service at approximately 17:50 today.

A malformed URL caused an unexpected error to be raised by a new version of the library we use for parsing URLs. With the decision making and logging service unavailable, our proxies failed close in order to prevent accidental exposure to harmful content.

Our engineers were immediately notified of this issue and a fix was pushed within 5 minutes.
