gin-nto-icore1 is a Tata router at Equinix in NY. Whether or not that port belongs to Comcast is anyone's guess.

Though I suppose if someone was photoshopping it, it would be pretty obvious for them to stick something that does show up in DNS into the graphs, so that doesn't exactly prove much. I'm also assuming Comcast wouldn't be very happy to have these out in public, so there is pretty much no way you're going to see a leaked graph that ISN'T from an anonymous source. FWIW these graphs pretty much reflect the massive congestion that I've been observing between Tata and Comcast. I've also seen some third party Smokeping graphs which visually show the rate of loss, and the pattern looks very very similar, but I'll let someone who actually maintains them be the one to post them. -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
