I have just reimaged stat1006. The machine is back in a productive state, and
we didn't need to do a restore of /srv.
The SSH host keys have changed. I have updated the corresponding wiki page
with the new fingerprints. You can also use the utility script to update
the keys automagically.
As always, if there is anything out of order, don't hesitate to contact us.
Note that tomorrow morning EU time, I will start the backup of stat1007, and
will reimage it on Monday morning.
