Tech:Server admin log

April 15

 * prod2 died, migrated to a new user and the set up was pretty much so hacky nothing worked really. Kudu knows more about that than me.
 * A key server file became corrupted and the server crashed. That account s for around 24 hours, then we moved to a new server and had to deal with a hacky set up which accounts for the other 40 ish hours downtime.
 * This is kinda bad to say this downtime happened while we were still looking at the old downtime.. so :/
 * At least we know *why* this one occured.
