Site Performance Degradation Due to Unoptimized Query

Incident Report for Highway

Resolved

After a recent feature launch, our production environment experienced elevated response times from approximately 8-10am on Monday 8/4. During this time, some end-users saw noticeably slower page loads and occasional time-outs. No data integrity or security issues were observed.

The slowdown was traced to an inefficient database query executed by the new functionality. Performance returned to normal after performing a manual update to our internal feature settings and did not require a redeployment of the application. A fix for the inefficient query was committed and deployed the evening of 8/4.
