Resolved after 7 hours 1 minute, affecting Canvas Proctoring and Blackboard Proctoring and 1 more, on October 21, 2026.
Status Update: Select Honorlock sites have been temporarily taken offline as a preventative security measure. Proctoring services remain fully operational. Cause: Active global exploitation of two newly discovered zero-day vulnerabilities in PHP. Taking sites offline is the only complete safeguard until patches are applied. This is a widespread PHP issue, not an Honorlock system issue. Resolution Plan: Official PHP patches are expected today. We will deploy the fixes immediately upon release and bring all impacted sites back online.
