Gack!  So that's what happened to my network last Sunday!

Even though the provider from which we get our service claims to be
multi-homed with Sprint and MCI, when the Sprint link was down, no
traffic was flowing through MCI.

OK.  I'll be recommending that the Sprint contract not be renewed.

And in the $10M RFP that just went out for one of my clients, I'll
specify during my bid technical review in September that any bids that
include SprintLink will not be accepted.  Enough is enough.
