Ouch. I've had 64ドル/mo dcanet over covad for a long time (connect

UPenn, perhaps that's the rub).
The Penn link has nothing to do with it, but the Covad line is probably
more expensive than their Verizon links. It definitely was when they
first offered Covad or Bell Atlantic, years ago.
Every/anybody connected to DCAnet's hub in Old City (which is really at
401 now) benefits from the back-haul link to Penn. It simply routes
traffic destined for Penn through that link (MAGPI.net) instead of
through their normal Internet backbone link -- Sprint, I think. Off
hand I don't know if DCA routes all the traffic on their network
destined for Penn through that link or only "old-city" traffic. All
traffic was the intent many years ago, but I don't know what their
routing topology looks like today.
In fact, depending upon which Penn sites you are after, you wind up
hitting the Akami server in 401 anyway.
Note that this link does not route THROUGH penn, but only TO penn.
Meaning, if you want to get to MIT you go through Sprint, not Internet2
from a DCAnet site.
[401 is 401 North Broad, the Datacom "hotel" in the city.]
