Performance Degradation in Customer Portal and Platform API
Incident Report for Yext
Postmortem

Summary

On June 11th, beginning at approximately 1:05 a.m. EDT, latencies in the Customer Portal and Platform API began to increase slowly. Yext engineers restored performance to normal at 5:20 a.m.

Root Cause

As part of our scheduled maintenance on June 9th, we conducted routine upgrades and security patching on a number of database servers. As a result of this upgrade combined with increased load, performance issues occurred that were not revealed in pre-production testing.

As a result, we have developed, tested, and deployed changes to relieve these performance issues. We have also completed modifications to our database operation procedures to add automatic safeguards that will prevent this class of issues in the future.
