For some reason, chat searches are not returning any results newer than July 8 at about 2:05 PM UTC. This example search pinpoints the issue.
The problem appears to be caused by the recent datacenter transfers. The time cutoff is apparently defined by the time the failover to Colorado occurred, and search began returning missing results after the failback to New York. It seems as if the search engine is running on outdated indexes that were not updated since the Colorado failover.
Can someone look into this?
Edit: This issue appears to be isolated to the
chat.stackexchange.com server. The other two chat servers are unaffected.
