Right, sorry about that.
The Vert server also hosted a bunch of Source servers (Gmod, etc). Recently, Valve decided that for some reason, Source should now use "Ubuntu Stable" packages instead of "Debian Stable" ones. We run Debian. During the update process, java got nuked. Not a big deal on linux, the servers would continue to run until shut down.
Nothing was lost, don't worry. The servers were shut down safely by hand. Backups were made and downloaded to 3 locations outside of the server itself; My computer, Jach's computer, and another server in the datacenter. Even the SQL was backed up.
Rather than trying to rollback everything in Debian (pretty much every package, ew...), we decided to take the opportunity to upgrade the hardware. We're moving from an E3-1270, 32GB DC 1600, 2x2TB HDDs RAID0 to a new box in the same datacenter with an E5-1620v2, 64GB QC 1600, RAID1 256GB SSDs and RAID1 1TB HDDs, which will run only minecraft.
TL;DR, sorry about the downtime. We expect to have the new server on September 1st, and I'll work as quickly as I can to get it online same day. IP will not change.
