Alex,

I would like to disagree with you on one point:

We actually did pull the trigger, as it were.  We came in on New
Years Day and turned on the filtering in the IMPs.  It wasn't
until the 2nd that most of the complaints started coming in.
Before the cutover, we had run statistics on which hosts still
had NCP packets coming in and out, and we also knew which hosts
were officially allowed to run NCP following the cutover, so we
had a good idea where the complaints would be coming from.
