Resolved after 2 days 19 hours, affecting Domain Categorization, on June 20, 2025.
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.
