Resolution of today’s web filtering issue

msherwood · September 21, 2022

This morning, you may have experienced an issue with the real-time web filtering component of our product blocking certain domains, including http://google.com. In addition, the Nebula console itself may have experienced slowdowns, as it was dealing with a high volume of alert traffic from the web filter.

Once alerted to the problem, our product team resolved the issue and released an update to our web protection database (version 1.0.60360).

This update is applied during the normal update process, and the issue should automatically resolve. In some cases, updating to the latest database may require temporarily disabling the web filtering feature.

Why did this happen? This morning, during a routine update, an error was introduced into the Malwarebytes web filtering database which caused various domains to be inadvertently blocked. We are performing an exhaustive analysis of our process to ensure an issue of this type does not affect our customers again, and we will be putting in place new procedures as a result.

We apologize for the inconvenience this may have caused you and your organization and remain committed to the highest standards of product quality and technical excellence.
