However MPLS hidden hops may hide internal paths, and any connection may
be limited to slower than its line rate, and dns entries may be
old....
It's
not publicly available at one source that I'm aware of, and if there is they
don't have my info.

Subject: Peering point speed publicly
available?
NANOG,
I have a question regarding
information on my ISP’s peering relationships. Are the speeds of some or
all peering relationships public knowledge, and if so, where can I find
this? By speed, I mean bandwidth (DS3, OC3, 100Mbps, 1Gbps, etc.). I
am trying to transfer large stuff from my AS, through my ISP, through another
ISP, to another AS, and I’m wondering how fast the peering point is between the
ISPs. I’m working with my provider to get this information as we speak,
but I’m wondering if it’s available publicly anywhere. If it were, this
could be one way to evaluate providers in the future, I
guess…
