>From what I have seen, I'm not sure these figures are accurate. Beyond the qualifications that you offered, another factor is the size of the network (i.e. if one carrier has three times the fiber miles and customers of another carrier but has the same number of outages, the "one is just the same as the other" argument might be a little tenuous.) I will check for a direct source, if I can find it, for NANOG list subscribers to access this information independent of any carrier or ISP.

Just did a story on this yesterday... http://www.nwfusion.com/news/0917starr.html 'Net braces for Clinton testimony By Sandra Gittlen Network World Fusion, 9/17/98 Forget the Starr report. The real challenge for the Internet could happen today with the release of streaming video of President Clinton's grand jury testimony. The House of Representatives could vote today to make public four hours of his testimony. House staffers are meeting with media executives to determine how to disseminate the tape and its accompanying documents on the Internet, according to Sharon Hammersla, computer systems coordinator for the U.S. House of Representatives. Online news organizations are rushing to figure out their plans for serving up the videostream. The 'Net has not yet seen this kind of anticipated demand for an audio and videostream, according to Katherine Dillon, vice president of ABCNews.com in New York. In contrast to last week's report, which consisted of roughly 450K bytes of text, the videotape could translate into many megabytes of data. In addition to the sheer size of the file, one issue is how to maintain a user's link for up to four hours. The Internet was not designed for such stateful connections. Dillon said ABCnews.com is in talks with video player creator RealNetworks to increase the companies' current hosting agreement. "We plan to broadcast the tape live as soon as it is made available," she said. However, she said that editing will have to be done to bleep out inappropriate language. She said she is also trying to increase her server capacity. "We have a T-3, but now we have to figure out how to load-balance the expected traffic," she said. "We're working out a plan with RealNetworks right now." In London, the BBC's online venture is also gearing up. BBC Online has capacity for 20,000 concurrent videostreams, said marketing editor Keith Roberts. The BBC has some experience with this sort of massive demand. Last August, the still nascent BBC Web effort was hard hit by mourners seeking footage of Princess Diana. Although the site did not crash, it did slow down, Roberts said. The BBC hosts its own RealPlayer video and audio servers separate from the main site's Web servers. "That way, if there is enormous pressure for video and audio, the Web servers for the site will not be affected," he said. Mindy McAdams, a Web strategist for the American Press Institute in Reston, Va., said media outlets should do more than simply serve up the feed. They should break the videotape into segments and label them clearly so users can go directly to the parts they are interested in. McAdams said one saving grace for media outlets is that not all of the estimated 20 million 'Net users that clamored for the Starr report have the video and audio gear installed on their computers to access the report. -- Sandra Gittlen Online Reporter Network World Fusion 161 Worcester Road Framingham, MA 01701 508-820-7431 (phone) 508-820-3467 (fax)

The Cidr Report

This is an auto-generated mail on Fri Sep 18 12:00:00 PDT 1998 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.

Currently we do it by connecting them directly to the Cisco's in each end, and do CEF based per-packet loadsharing, it works fine, but support a max of 6 E1's ... I've been thinking om something similar to the Larscom inverse MUX (http://www.larscom.com/t3ft3/t3_megae.htm) but this one only support 4 E1's, then I can use multiple i-mux's and loadshare over the 8M links they provide, but it seems like a poor solution.

There IS a difference. The FCC keeps records of outages which must be reported by the carriers. It is worth checking these out.

Do they have any redundant rings? Looks like their growth has >been too agressive for sound SONET engineering efforts to be employed. >But, hey, they have a lot of glass... I don't have my papers at home, so this is my recollection. Over the last four years cable cuts and other physical outages seem pretty randomly distributed between AT&T, MCI, Sprint and Worldcom. Some years one carrier has more, other years a different carrier has more. However the affect of an outage has not been equally distributed. Each carrier has its strengths in different markets. Worldcom happens to be fairly strong in the Internet circuit market so you read about Worldcom cable cuts on Internet lists. If you were a financial type, you would have thought MCI had a lot of problems. Remember the cable cut in Manhatten earlier this summer, it affected some Internet traffic but the brokers on wall street were livid. If you were an airline, you would have thought AT&T had a lot of problems. Sprint has problems, but I don't know which market segment it is really strong in. Salespeople for each of the above companies are usually more than willing to give you information about the reliability problems of their competitors. Getting information about their own company is harder. I doubt backhoes or gophers will show any favoritism for or against cable installed new competitors such as Qwest or Level3.
