FLASH CROWD: media stimulated simultaneous usage event
by Sean Donelan 11 May '99

11 May '99

Unless you've been off-planet, I think most people in the US are aware Star Wars tickets go on sale on Wednesday May 12 at 3pm EDT via phone, web, and box office. Some folks may remember a few years ago when Garth Brooks tickets went on sale in Washington DC, and the local phone system was overwhelmed for most of the day. And during the Gulf War the Pepsi Company was requested not to run a contest during the Superbowl involving a 1-800 number. I happen to be in DC for an ATIS meeting, so it should be interesting to see how many telco-types are beeped out of the meeting during the day tomorrow. I've been checking around, and found in most cities the movie theatre tickets-by-phone numbers are not on the local "choke" exchange. Instead they are dispersed on whatever exchange the theatre happens to located. This may not be a problem in cities with modern switches, because they can program full-10-digit "chokes." National 1-800 service (SCP/STP) may be hit by a large number of call-attempts, and re-dials as people try to get through. The "redial" button is an evil invention as far as telephone switch design is concerned. Local PBX's of companies with a lot employees interested in the movie may also experience overloading. Due to the way the Internet traffic fans out (see the CAIDA maps), I would expect only localized hot spots near the tickets-by-web sites. The Internet doesn't have centralized control points like SCP/STP's, so Internet users should be unaffected except for those particular ticket web servers and possibly those sharing the same subnet or same last router as the ticket web servers. NOC managers may want to keep this event in mind if they need to reach other NOCs tomorrow afternoon, or if they need to call in their own engineers if something happens. You may need to use alternate contact methods to reach them. On the other hand, perhaps the American public has reached the hype saturation point, and nobody will buy tickets tomorrow. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

Could be a few different reasons. a) Curiousity b) Concern it may have a root cause shared by other providers c) Lack of notification via formal channels d) Spite e) All of the above What's the only thing worse for a network engineer than having his network crash? No one noticing it crashed. I'm really surprised more providers haven't figured out one way to keep people from posting about their outages is by setting up peering agreements with NDA's and then keeping the other providers informed about problems. Of course if there isn't an NDA or they learn about the outage from other sources, they are free to inform the world about the outage. Oh well, another Sprint exec Gerry Degruiter is going to stop by next week. I hope he can tell me why our Sprint line failed last November, no one else has been willing too. I'll keep you posted :-) -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

The Cidr Report
by Tony Bates 07 May '99

07 May '99

This is an auto-generated mail on Fri May 7 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.
