I just tracerouted ArsDigita as Phil suggested, and it produced an interesting result... aD has jumped AboveNet's ship and switched to the Exodus bandwagon (which seems to house every major website in the world these days). Tell us it ain't so, Phil! Or at least tell us why, if you get the chance to update this page... to the layperson (i.e. me), it would seem that AboveNet (having 380 peering agreements to Exodus' 250) would be the superior solution on a pure connectivity basis. Is aD using some of the "value-added" services that Exodus offers and AboveNet does not? On an unrelated note, I wanted to point out to this community that the AboveNet colocation service starts at around $1300 now, as a result of a new pricing structure that doesn't dip below 1 mbps.
Big Hosts may help anyone who doesn't have the $1000+/m to pay AboveNet or Exodus. It is a brand new resource and hasn't caught on with all the advertisers yet (which make the spotlights work), but there are some good articles from a layperson perspective for one to peruse. Tell me what you think by emailing me. Good luck with your search for a good colocation (or dedicated server) provider.
