[Cryptech Core] cryptech server yoyo

[Rob Austein]

Apologies for instability with cryptech.is servers this morning.
The KVM box that hosts all the VMs got tetchy about some maintenance
upgrades and refused to boot.

At this point we think we've cleaned up the resulting mess and will be
done breaking things after one more reboot to get into a known clean
state, but if this is the last message you see for a while and the
servers are down again for an extended period, you'll know why.

Will send another message when we're done.
