[admin] system crash and future downtime

I was disconnecting the monitor from firebird (the Phoenyx machine) and
accidentally pulled the power cord out of the box about twenty minutes
ago.  (Why don't power cords have little screws on them like everything
else?) 

It came back up with a corrupted file system, but unlike DOS/Windows it's
much harder to corrupt the whole disk under Unix.  Looks like we lost
three inconsequential files (two administrative email messages and one
bounce message from the mail queue).  The file system check/recover seems
to have restored the file system to the proper condition, but there's
always a chance something got interrupted and didn't write out entirely.

Watch for any odd behavior and let me (support@phoenyx.net) right away if
you see something odd.  Especially watch your listowner report in the
morning to see if the number of subscribers looks correct.  We did a full
system backup this morning, so we haven't lost much if we have to pull
something off of the backup.

All that said, I had *intended* a short period of downtime today to
install a new hard drive and still plan to do so around 4 or 5 PM (CST).  
Any mail aimed at phoenyx.net will get queued on the sending system for
(usually) up to five days.  It won't even report a warning in the first
four hours, so as long as it's back up within that time your users won't
notice anything but a delay in processing their mail.  I don't expect it
to be down for more than an hour at most... I'm just installing the
hardware.  Once that's done and I have time to partition and format the
drive, next Sunday or so I'll take the system down again to transfer the
data from the old disk to the new *and* upgrade to Debian 2.1.  (By doing
the upgrade at the same time, if something goes wrong I don't have to
restore a backup... I just stick the old disk back in.)  That'll probably
take a couple of hours, but according to our activity logs, Sunday
afternoon is by far the slowest period during normal waking hours.  
(Sorry, I'm not quite devoted enough to get up and do this stuff at 2 AM.

Don't bother pressing that key, there is no Esc.
