I sure wish I knew what caused that. It happens very steadily, with 
deep loss periods, on all the multicast traffic from Northwestern to 
me. It also happens on occasion on traffic from Columbia. I've done 
some poking to try to nail it down but haven't been able to isolate 
it, or even solidly identify in what portion of the network it occurs 
other than to say I don't think it is inside my own backbone. . . but 
I'm not even certain of that.

Bill.
