The Cidr Report

31 Mar '00

This is an auto-generated mail on Fri Mar 31 12:00:00 PST 2000 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

Gravity is a tough law to break. Batteries and mechanical equipment are heavy, and must go where the floor is strongest. Which tends to be the core of the building. As always consult a licensed structural engineer. Protecting against an airplane crashing into the side of the building is hard (although the Empire State building survived).

Another note about battery rooms in high-rise buildings. There is/was a proposal before the NFPA to prohibit battery rooms above the third floor in high-rise structures after the L.A. CO fire. I haven't been keeping close watch on it, but Bellcore/Telcordia was fighting it tooth&nail.

RE: independent publication (was Re: DSUA) (fwd)

A paper publication brings an important element - the market. Folks have to pay large $$$ for paper journals. This allows a process known in capitalistic societies as "voting with your feet". If you feel a particular journal or it's peer review policies have become corrupt, you don't pay for the journal anymore. The journal then ceases to be. Other than a governmental approach (as if ICANN could remove the IESG's "mandate from heaven"...), an approach anchored firmly in the value of currency is pretty sound. The other side of this coin is that there is typically a professional society backing the journal. Is it time for NANOG to become that type of organization? (i.e. AMA, ASME, ABA, to name just a few). As most employers will pay for professional society dues and journal subscriptions, the economic impact on the actual participants would be minimal.

one of the problems with higher is that people trapped below would be subject to immersion in liquid acid from the run down and people above from the burning fumes, not a good choice. Option 3 for large network carriers, large data centers that are in non flood plains or high storm zones.

I don't speak for Telcordia, but I believe their position was somewhere along the lines that a total ban was not needed. Its like banning all electrical wiring above the 3rd floor because fires have started in electric wires. Instead Bellcore offered an alternate proposal with rules how such battery rooms should be constructed to mitigate the risks. The nicest battery plant I've ever seen was at the Bellcore training facility outside of Chicago. On Thu, 30 March 2000, "Henry R.

Southwestern Bell says there was some network congestion, but no telephone network failures. TXU says 30,000 customers lost power. Emergency service officials report the 9-1-1 PSAP in Fort Worth was overloaded during the storm, but calls were redirected to mutual aid PSAPs including Arlington. The FBI and ATF offices were essentially destroyed. Part of downtown Fort Worth is expected to be closed due to the danger of falling glass through Wednesday morning. One company has already issued a press releases saying their data center in the area is operational. Most of the Internet facilities are concentrated on the Dallas side of the metro area.

Shh! That's our secret. The sales folks think we're giving them great window offices, when we're actually building the crumple zone :-)

We've just released a Palm VII app so you can do whois queries from Palm VII and compatibles. We should have a comprehensive www.geektools.com Palm Micro App in the next short while. Additionally we're trying to get a good WAP / Web Clipping app going as well.

MCI's public relations person reported the fiber cut yesterday was in Florence, NJ; other NOCs have told me the fiber cut was in Moorestown, PA. For my own information, did anyone actually see it, and can confirm where the cut was, or if there was in fact two cuts.
