We were experiencing issues with search in pod 4 briefly. The situation has been mitigated.
During this incident, customers' search functionality was affected. This was a brief reoccurrence of the Pod 4 search issue that occurred on January 26. An unexpected change in ingested data caused a sudden increase in heap usage, resulting in expensive garbage collection cycles which in turn made some of the search servers unresponsive.
We continue to investigate the complex query string that was being sent to search that caused the change and are working on improved logging of search service queries that are timing out.
