[ This message is being sent to various mailing lists and individuals that

Beginning Thursday, October 16, at approximately 1:30 PM Central time
(UTC-5), the server became unreliable and was unable to keep
services running for more than a few minutes at a time.  Finally, it became
almost completely unusable.  I still do not have a clear idea why that
occured, though the hosting provider spoke of a denial of service attack. 
The short version is that things are back up, and if they don't look normal
to you yet, they will soon.

The more detailed story:

As the machine had not yet returned to normal service by that evening, I
obtained space on another server.  Today, all functions were moved over to
the new server and things are returning to normal.  Some things may remain
inaccessible for the next few hours while DNS changes propogate.

Here is the impact this had:

 * E-mail: mail was not delivered, but backups were in place.  My best
   belief is that no mail was lost.

 * DNS: All zones for which is primary have a secondary
   nameserver in France.  No practical interruption of service should have
   been felt.

 * Web: Websites hosted at were down during the outage and are
   now back up.

   Exception: (aka is not yet
   back up, and it will be a day or two before it is. 

 * Gopher: was down, and is now back up, except for the mirrors,
   which will take up to a week to restore.

 * Subversion and Arch repositories: fall under the Web category
