Outage in Cisco Umbrella
Cisco Umbrella - Oracle domain access issues with Generative AI application controls - Global
Resolved MinorIncident Report
Summary AI Generated
A misconfigured update to Cisco Umbrella's Generative AI application category incorrectly classified Oracle-related domains (including oracle.com) as blocked content, cutting off customer access globally for approximately 41 minutes. The erroneous change, tied to an updated "AI database" application definition, affected both DNS and Secure Web Gateway (SWG) access. Cisco reverted the change to resolve the issue, with SWG access restored first, followed by full DNS access shortly after.
We are investigating an issue where Oracle-related domains (including oracle.com) are currently being blocked in Umbrella after a recent update to the Gen AI application category. This appears related to an updated "AI database" application definition that is affecting multiple Oracle domains under Gen AI app controls. We have reverted the recent change and are closely monitoring web and DNS traffic to confirm full restoration of access for affected customers.
