Is it really important to know the link speeds? What good does it do
without knowing
about the loading on those links?
I would MUCH rather have an empty T1 than have to contend with a very
oversubscribed OC-768.

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…
