About This Site

Due to the redundant nature of our anycast infrastructure, DNSFilter services including DNS layer security, content filtering and resolution are always available. In the event of regional downtime, DNSFilter automatically switches to the nearest data center with no manual intervention. By design, our core services will not be disrupted by planned or unplanned outages.

As such, via our status page, DNSFilter strives to provide complete transparency for the current and past status of our service.

Domain Categorization & System Load
Resolved - This incident has been resolved.
Jun 23, 08:51 EDT
Monitoring - What Happened with Domain Categorization and System Load (e.g. msn.com )
-Some well-known domains like msn.com and started showing up as “uncategorized,” and our backend systems experienced a large spike in traffic. Here’s what we know:

What Happened:
-Some websites like msn.com temporarily lost their category labels due to them being treated as uncategorized in the system.
-Our platform automation tried to correct this but sent too many repeated requests at once, overloading internal systems.
-This caused delays in restoring correct category information, so some domains stayed uncategorized longer than expected.
-We’ve deployed a fix to reduce the load and are restoring normal behavior.

Key Customer Impact:
-Domains like msn.com appeared uncategorized because they dropped out of cache and couldn’t be reloaded reliably.
-This could affect content filtering accuracy, especially for high-traffic or policy-critical domains.
-No DNS resolution outages occurred, but policy behavior may have been incorrect.

Fix:
A fix has been implemented; however, due to caching, it may take 24–48 hours for affected domains to reflect the correct categorization.

Workaround:
In the meantime, you can either add the impacted domains to your allow list or temporarily allow uncategorized domains within your policy settings to avoid disruption.

Temporary Query Log Disruption – No Impact to DNS Filtering
Resolved - Between hour 5 to 6 UTC today, a networking issue outside of our control was detected between our AnyCast nodes across the world and our query log eventing system.

DNS Resolution and Filtering were NOT affected.

The networking issue has since been resolved but as a result you might notice that on a daily basis, about 2% less query log entries than a usual weekday in our Query Log.

We are working with our networking partners to ensure this does not happen again and we are putting extra safeguards in place to avoid this in the future.
