The Cidr Report
by Tony Bates 21 May '99

21 May '99

This is an auto-generated mail on Fri May 21 12:00:00 PDT 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

Long live SPAMOG. "When did you stop beating your wife?" Sure, real time updates on other people's network problems are less despicable than discussions on spam or smurfing. However, for those who have subscribed to nanog for more than 3 years, nanog has traditionally been useful to discuss operational issues, where issue is defined as a concept or problem. Real time issues are generally helped little by nanog discussions. <sarcasm> I'm looking forward to all of the real time network health and T1 cut updates at next week's NANOG conference. </sarcasm> -alan

In retrospect, it's obvious... The reason Sean was beaten in reporting this cut was, after he got off the backhoe, he couldn't find a working NoNuts payphone to logon & file his report... -- A host is a host from coast to coast.................wb8foz(a)nrk.com & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433

NYC FIBER CUT 5/19/99 (v2.0)
by I Am Not An Isp 20 May '99

20 May '99

I have some more info on the fiber cut in NYC. It is right outside the 111 8th Ave. building and *appears* to only affect people in that building. (Prolly hit the conduit going into the building, not the main fiber loop - but I can't confirm that.) The ETR has been changed. It was 8 hours as of ~9:30 AM PDT. (*Much* longer than the original estimate.) I'll try to keep you updated as I get more info.
