Incident Report

Summary AI Generated

Cisco Umbrella experienced intermittent timeouts with their block page service affecting customers connecting through the LAX data center, where blocked websites would fail to display the expected block page instead of loading properly. Users could work around the issue by refreshing the page to potentially route to a healthy node. The issue was mitigated after 7 minutes and block pages returned to normal functionality.

We are investigating a potential issue with the block page service affecting customers connecting to the LAX data center. Some customers may intermittently experience timeouts when attempting to access websites that are blocked by policy. In these cases, the expected block page may not load. Refreshing the page may route the request to a healthy node and display the block page as expected. Our engineering team is actively working to restoring full service as quickly as possible. Updates and additional details will be provided as new information becomes available. We appreciate your patience and understanding during this time.
