Resolution to Earlier Lag Issues - COMPLETED
Our host identified the problem and has resolved it. Their abbreviated response:
We determined this problem was being caused by mishandling of certain types of traffic on two distinct carriers simultaneously, while other carriers were unaffected. We did not identify any problems on our network equipment. Both affected carriers have been removed from our network until we have confirmation that they have fixed the underlying problem. Even with these carriers out of service, the network retains sufficient capacity for normal operations.

P(a or b ... or z) = 1 - P(!a and !b ... and !z)
