To what end? And who's calling the shots there these days? Comcast has been nothing but shady for the last couple years. Spoofing resets, The L3 issue, etc. What's the speculation on the end game?

Yeah, the 30 day looks like a classic uptick in traffic toward the holidays. Some bellhead beancounter maybe took out capacity in the summer lull and ignored the engineers. Or they just have stupidly-slow install intervals. Same crap I've seen on loads of provider networks.
Except that they seem to be busy actively turning down other capacity, and forcing extra traffic through their Tata ports by blocking other paths with BGP no-export communities. For example, we've been observing Comcast turning down some of their Global Crossing capacity in recent days, causing new congestion during peak traffic times. I've even seen people contact the various NOCs involved, and they've been told explicitly and by multiple parties that Comcast is intentionally turning down extra capacity and running their existing ports hot. Everybody who deals with interconnection capacity in this industry knows what's going on, but the graphs and interconnection details are all under NDA, so it takes an inside source secretly leaking graphs to the public to expose this kind of activity. Even then you'll still have people who claim that it proves nothing because the graphs can't be positively associated to a specific customer port, but realistically these kinds of leaks are probably the best public info you'll ever see. -- 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) _____ No virus found in this message.
