The Cidr Report

This is an auto-generated mail on Fri Dec 24 12:00:00 PST 1999 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

I don't know about where you live, but around here they've been saying "please don't pick up the phone right after midnight just to test it, if everyone does that it will crash...". Loudly, on TV, getting the local stations to spread the word... -george william herbert gherbert(a)crl.com

NO NETWORKING DRIVERS ENABLED Good grief Charlie Brown, it was a joke. C2 certification means about as much as Y2K certification. There are so many qualifications they are meaningless in any real world situation. It's another checkmark you have to make on the paperwork before winning the bid. I know my laptop is ready because it came with a Y2K-ready sticker on it. After I brought it home, I only needed to download a half-dozen different patches for Y2K, security, and just plain bugs. The issue of being C2 certified only as a standalone workstation is hardly unique to Microsoft NT. As far as I know, ALL the C2 certified operating systems Unix, VMS, VM, etc are only in standalone mode. Others, such as Linux, aren't certified even in standalone mode (well, maybe in the unplugged, encased in concrete, and dropped to the bottom of the ocean mode). If that wasn't a troll, I don't know what is.

After Y2K, critical infrastructure

After Y2K settles down, the most likely next bandwagon will be so-called critical infrastructure or Cyber-assurance. If you look behind the curtain, you will find many of the people involved in the Y2K hype are actually from the the critical infrastructure programs which got side-lined this year due to Y2K. I expect when they return to their "regular" jobs, they will want to keep the extra money they got this year for Y2K as part of their regular budget next year. I'm hoping the "hackers" will party and get drunk over New Year's, and leave the so-called critical infrastructure alone. If you think you filled out a lot of paperwork for Y2K, and you ain't seen anything yet. I for one sleep much better knowing Microsoft NT is certified C2 ready :-)

Wasting an entire 2 billion seconds to check for a -1 error condition instead of the one's complement 0xFFFFFFFF is remarkably stupid imho. But it would break a lot of userland programs to change.

Floods Telcos and FCC outage reports
by Sean Donelan 23 Dec '99

23 Dec '99

The New Jersey state utility commission completed its investigation into the Rochelle Park, NJ central office failure due to flooding this fall. Bell Atlantic originally reported the cause as a dam breaking and water entering through doors left open by AT&T. AT&T disputed the report filed with the FCC. The state board investigators found no dam had broken and water had entered by a number of entrances, including cable vaults, basement plumbing fixtures, as well as the rear door. Bell Atlantic's report didn't mention the flood water entering through other entrances. The state board couldn't conclude whether any one source was the cause of the shutdown of the power plant at the central office. The board ordered both Bell Atlantic and AT&T to make improvements, investigate the flood risk at other locations, and report back to the board. Bell Atlantic stands by its report, except they now agree no dam broke. The FCC's investigation is continuing. Source: Bergen County Record http://www.bergen.com/news/flood23199912234.htm

Re: Internet Y2K Conference Call

Does anyone know how many conference calls will be in progress over New Year's. AT&T is providing most of the teleconference bridges for the big Y2K groups (ICC, I0PS, etc). There's something to be said for one of the few telephone companies that has experience with '00 rollovers, being incorporated in 1885. But I've also seen press on MCI Worldcom having many different conference bridges operating over New Year's. And I assume the same is true of other teleconference providers. Will this be the "mother's day" of conference bridges? How many simultaneous conference calls can the current voice bridge infrastructure support?

Silly season
by Sean Donelan 23 Dec '99

23 Dec '99

As Alan points out, it looks like silly season will be in full swing. Here is a site claiming it will check the top web sites in the world, and if 5% aren't responding at 1 minute before midnight (pick your time zone) a major disaster has happened. http://biz.yahoo.com/prnews/991222/inferno200_1.html As has been pointed out before, many sites plan to shutdown their web sites or disconnect from the Internet over the New Year's weekend. Which I guess is a self-fulling prediction. The Internet is still considered an "extra" and not a necessary connection like the telephone or ATM. I haven't heard anyone suggesting they would turn off their ATMs, even though they are Y2K ready, just to be safe. You can read ATM as representing either acronym.
