Around 1PM ET on February 4th 2021, telemetry indicated that Answers query logs were not being populated into our Analytics system, thus preventing them from appearing in several places within the Answers and Analytics platform. Engineers identified the problem and were able to backfill the queries and repair the pipeline into Analytics by 4:45PM ET. No data was lost.
The piece of Yext software which processes Answers query logs was unable to properly interface with the open source software which stores the queries. The problem was relatively simple, but was exacerbated because we did not have an easy flag to enable the required debugging.
We have designed tooling to facilitate debugging in real-time, thus enabling us to diagnose issues of this kind more readily.
