I performed an apt-get dist-upgrade on approximately thirty 12.04.3 servers this morning (mostly VMs, some installs on hardware). All of those servers are now reporting 12.04.4, and 7 of them (6 VM, 1 hardware) had Apache 2.2 upgraded to Apache 2.4 (which broke a ton of stuff). There are another 15 or so servers still running Apache 2.2, and I can't figure out what forced the 2.4 upgrade on those specific machines.
I thought 12.04.4 wasn't going to be released until the 6th of Feb. What happened?
Note: I'm in Australia, would something to do with local APT mirrors be the cause?
