Customer Impact:
Hearsay deployed an update where an index was added to a database. This resulted in an increase in CPU consumption, which led to Hearsay’s users seeing an error page on our platform. There was no data loss during this time.
Resolution:
Hearsay’s engineers identified the regression and reverted back the change to our database.
Future Improvements:
Hearsay will add more internal alerting with more aggressive thresholds to ensure we act even faster if this were to reoccur. Additionally, Hearsay’s engineers will avoid making similar changes during, or close to, business hours.
