This one can be harder to get any answers on depending on who you are.
You can ask what locations they have most of their peering with.  Also ask
for a POP list they are located in.   Usually they are marked with the type
of service each building is (pop vs metro ring vs extension).    unless
it's a private peer, I woudlnt' expect any peering at locations that are
not pops and you can see what is nearby your location that is a pop.

Somethign else I just thought of that I do ask providers.   Ask how they
get into your building.   If they are using some sort of metro ring between
their routers make sure your not about to screw yourself with no diversity
when that ring needs to be worked on.
