Internet demand and power shortages
by Sean Donelan 16 Apr '01

16 Apr '01

Regulated utilities seem to like to blame the Internet for the world's woes. First telephone companies scared the world with claims the Internet would disrupt 9-1-1 services, and now electric companies claim unprecendented demand from Internet companies is leading to power shortages and rolling blackouts. >From the April 15, 2001 Contra Costa Times: > The theory that the Internet sucked up the power grid and launched > an era of rolling blackouts is staunchly rebuked by academic experts, > who say much of today's demand follows population and economic growth > trends.

If you add all telecommunications and electronics manufacturing it rises to 3% of the total US electric power consumption. The upper limit on the Internet's consumption contribution from a different memo is 36TWh/year.

Some providers do a better job than others. If you provider doesn't do a good job, you should consider taking your business elsewhere. There is nothing posted on public mailing lists or reported on the wireservices your own provider couldn't tell you if they chose to. Different providers have very different cultures regarding informing customers. Everyone has problems, how they deal with the problems varies between providers. Historically, I've found these providers consistently have the best customer notification processes, year after year. This has nothing to do with how many problems a provider has. A provider may only have a single problem a year. 1. Genuity 2. AT&T 3. Ameritech (the NAP not the rest of AADS) Most providers fall in the middle ground. After a big problem, they get on the customer service train for a few months. But tend to fall back into their former habits. But like the Grammy's if you divide up the market enough ways, everyone can be number 1 in some catagory.

Channelized STM-1
by Arnold Nipper 14 Apr '01

14 Apr '01

Two questions concerning channelized STM-1: 1. Do I have to order a special type of line on the "slow" end? Or will a ordinary E3 be sufficient? 2. What type of gear do you recommend for the "fast" end?

The Cidr Report
by Tony Bates 14 Apr '01

14 Apr '01

This is an auto-generated mail on Fri Apr 13 23:00:02 PDT 2001 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.

> purchase connectivity from them, even if their network didn't suck. What makes you think this? Perhaps you can share your experiences that would substantiate this claim. I have rarely seen cross country RTTs exceed 70 msec (right now it's 58msec from nyc to sfo) and don't recall the last outage they've sustained on an edge router, let alone core disruption. I also hear people discuss their lack of peering, however recent Skitter plots show them sitting pretty close to the origin. Regards, chris

While I agree that the initial message from the Qwest folks was excessively terse, and the final follow-on response at best unprofessional, it certainly wasn't without provocation, IMO.. Likewise, I'd really rather not see a new trend develop here where folks whop some sales droid and then whine to NANOG when they're whopped back. Leave it on inet-access, it doesn't belong here (nor do lots of other things, of course)... As well, having first hand knowledge, I would contend that a number of their networking people indeed "have a quarter of a clue between them", especially when speaking relatively. -danny
