There was a problem with our data center today, creating a site outage (server unreachable).
That problem has been resolved.
Basically, it seems to have been a socially engineered denial-of-service attack against UNIX.com; which I stopped as soon as I found out what the problem was.

unlog
UNLOG(1) AFS Command Reference UNLOG(1)
NAME
unlog - Discards all of the issuer's tokens
SYNOPSIS
unlog [-cell <cell name>+] [-help]
unlog [-c <cell name>+] [-h]
DESCRIPTION
The unlog command by default discards all tokens that the issuer currently holds. To discard tokens for certain cells only, name them with
the -cell argument.
Since a token pertains to one client machine only, destroying tokens on one machine has no effect on tokens on another machine.
CAUTIONS
Specifying one or more cell names can cause a brief authentication outage during which the issuer has no valid tokens in any cell. This is
because the command actually discards all tokens and then restores the ones for cells not named by the -cell argument. The outage can
sometimes interrupt the operation of jobs that require authentication.
OPTIONS
-cell <cell name>+
Specifies each cell for to discard the token. If this argument is omitted, the Cache Manager discards all tokens. Provide the fully
qualified domain name, or a shortened form, in which case successful resolution depends on the availability of a name resolution
service (such as the Domain Name Service or a local host table) at the time the command is issued.
-help
Prints the online help for this command. All other valid options are ignored.
EXAMPLES
The following command discards all tokens.
% unlog
The following command discards only the tokens for the "abc.com" and "stateu.edu" cells.
% unlog -cell abc.com stateu

None
