What we're dealing with here is still the effects of the Welchia worm/virus.
We haven't had the resources to contact everyone whose computer is infected,
and have them correct the problem. We're working on another round of
notifications, so once those go out, and we get some compliance, things
should be better.
I suspect that one of the reasons the ACD DSL service is better is because
there are more customers on the MSU IP's than the ACD IP's. Or perhaps
ACD has an easier time contacting their customers which are infected
(MUCH smaller user base). For the record, yesterday evening, my monitor
picked up 4 infected computers in ACD's East Lansing territory. That's
apparently more than enough to swamp the network.
