I think you've hit on it BBW. Actually there is a technical term for what occured. "FART."

Faulty_Access - Routing_Terminated

These problems usually don't last long as the system reboots and releases the "GAS" (Governing Access System)of excess demands on it and false reporting of system ISP terminal originating signals.

Sometimes there is a minor "FART" in a system called a "TOOT" (Technical Overload Often Temporary) and these are generally unobserved by users even though they occur often they are the kind most people don't notice.

At any rate, I hope this technical explanation makes sense to you all. Sounds like things are back to the pre-2.0 change over. :)
