We just rotated (literally) some machines at the hosting facility and brought one of the new machines (catbus) into service as our new database server. Bender, which was previously the DB and TRM server, will now solely be used for TRM service, which should decouple the TRM generation from the rest of the MusicBrainz site.
Hopefully this will bring more capacity to handle users to MusicBrainz.
Big thanks to Dave Evans and Kevin Murphy for their help in making this happen.
