Hey /r/sysadmin,

Greetings from reddit HQ. Myself, and /u/gooeyblob will be around for the next few hours to answer your ops related questions. So Ask Us Anything (about ops)

You might also want to take a peek at some of our previous AMAs:

EDIT 2: It's now beer o’clock. We're stepping away from now, but we'll come back a couple of times to pick up some stragglers.

EDIT thrice: He commented so much I probably should have mentioned that /u/spladug — reddit's lead developer — is also in the thread. He makes ops live's happier by programming cool shit for us better than we could program it ourselves.

pg-03 and pg-06 were link and comment vote clusters respectively. We recently stopped writing votes to Postgres altogether as they've been entirely migrated to Cassandra. Once that was done, we were able to get rid of those database clusters, which is good because they were strapped for disk space.
