Customer Impact:
Users interfacing with Hearsay Relate via web, mobile app, and Embedded Relate with Salesforce may have experienced slower-than-normal page loading times or error messages during this incident. This was due to an unexpected high number of API requests to a specific endpoint, which resulted in an inefficient query pattern that caused a slowdown in our database systems. There was no data loss during this incident.
Resolution:
Yext’s engineers quickly identified the source of the problem and temporarily reduced the throughput for this specific operation to allow the database to recover. This restored performance for all users.
Future Improvements:
Yext is already in the process of implementing rate limiting on all public APIs, and continuing to enhance our monitoring systems to detect unusual database patterns earlier.
