What's up at NTL/VirginMedia?
by Alexander Harrowell 07 Aug '07

07 Aug '07

Seems to be a large-scale outage going on at Virgin Media ex-NTL, AS5089 in the UK. Lost service about 1600GMT yesterday to a wide range of locations throughout the country. Recorded phone message now saying several post code areas in SW London suburbs still dark, but status page shows lots'o'tickets open all over the country. Anyone know what's up?

Hello former DI peeps out there! :-) Digital Island got the Footprint CDN when we acquired Sandpiper Networks for ~$600m back in 1999. Also, Exodus (back then known as the Evil Empire to many DI folks) never acquired DI. The Cable and Wireless US Division acquired both DI and Exodus, renamed everything to "Cable and Wireless America", performed the largest mass destruction of value many of us have ever seen (I believe over a billion dollars) and then went into bankruptcy. Then Savvis bought the Footprint part. Finally, Level 3 bought Footprint from Savvis. I believe this is everything... Ahhh, the bad 'ol days... >;-) scott --- patrick(a)ianai.net wrote: From: "Patrick W. Gilmore" <patrick(a)ianai.net> To: nanog(a)merit.edu Cc: "Patrick W.

I am not sure why you would say Akamai is "tailored to pushing relatively small files", since I do not believe they say that anywhere. LLNW does say they are focused on larger files. (I believe LLNW claims Akamai is focused on smaller files, but do you believe what Akamai says about LLNW?) I can confirm that Akamai does not have a backbone. Neither does Panther Express, CacheFly, or Mirror Image. While Level 3 (who owns Digital Island, which they bought from Savvis, who got that when they acquired Exodus, who bought way DI back when), LLNW, and at&t all have their own backbones. > Any insights out there? And what are the major challenges in making > scalable content delivery networks? Myriad. Some are hard to overcome, some are very hard. Keyword here being "scalable" - which you failed to define. What is "scalable" to you? 100 Gbps? 500 Gbps? The latter is medium-hard in the US, the former is nearly impossible in South Africa. Which brings us to geography. Are you US-centric? European? Asian? Six continents? Just a few specific countries? Plus, as you mention above, there's file size. How about streaming vs. HTTP? Optimize for latency or throughput? Did I mention cost? Etc., etc. If someone asked "what are the major challenges in making scalable backbones?", how would you answer? -- TTFN, patrick

It's harder than it looks, given the number of people who pop up on this list and ask how to get BGP to Do The Right Thing when 2 paths are the same length but vastly differing in bandwidth, number-of-actual-hops, and/or latency....

If there is anyone with a clue at AS32445, or their adjacent networks (which appear from here to be AS174 & AS5769) could you please contact us at noc(a)forest.net, or +1-206-838-1630, ext 2031. We've had an ongoing DoS attack from your network for the past two days. It would nice to stop it at, or close to the source. Thanks. --chuck

seems i've been ignoring it for two years. sorry about that. all the mail i had on this topic has been processed. check your entries. i'm in the mood for more updates if anybody's got anything. note that CCCP died and i replaced it with an entry for SFCCP, don't know if that's correct. i'd like all community colo projects in the world to be listed.
