Things on infosec.exchange were getting a little bit sluggish, and I've had complaints about media processing taking a long time so I added another app server for the US region. In the past, that has caused media uploads for some people to just fail outright because the reverse proxy hops the upload from one app server to another - and the other has no idea what to do with the last half of a file. I am hopeful I've got that problem ironed out in the nginx config, but would be interested in knowing if anyone runs into that...
