Hi all,
Cutting and pasting from my blog entry[0] because I'm lazy:

Again, please accept our apologies.  The decision was made a long time
ago to not back up $HOME, and it was mentioned a few times, but
certainly not documented nearly as widely as it should've been (i.e.
shouted from the rooftops), given that a few people have lost data and
been upset about it.

The plan for when we get new hardware is to run the old hardware as
redundant backups, with regular rsyncs, so we can fail over and have
less downtime, as well as have a backup (of sorts) of $HOME.

Hopefully this doesn't put you guys out too much, and thanks for your
