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.]
