I'm looking for some pingable nodes in LA / Dallas / Chicago / NY for any of the above listed providers. BGPs including premium bw providers, and excluding cogent / yipes / timewarner / wiltel , etc I would able be interested in looking at. Please include the name of the provider for BGPs.
22.214.171.124 - Mzima LA
126.96.36.199 - Savvis Dallas
These *may* not be the absolute best nodes to ping for each provider, but happen to be the gateways for my servers at those locations. That should at least be a step in the right direction, for what its worth
