UUNET instability?
by Streiner, Justin 25 Apr '02

25 Apr '02

Anyone else seeing routing instability through UUNET or have any more details? I saw a significant drop in my inbound and outbound traffic to them around 10:00AM EDT. UUNET has a prompt on their phone menus about network instability, but didn't elaborate. Their NOC doesn't have any more details as of yet that they're passing along. jms

The Myth of Five 9's Reliability (fwd)
by Pete Kruckenberg 25 Apr '02

25 Apr '02

>From the Canarie news mailing list. I don't think I've ever experienced five 9's on any telco service, I have always assumed I must be the one customer experiencing down-time, and the aggregate was somehow five 9's. How is network reliability calculated to end up with five 9's? Pete. ---------- Forwarded message ---------- Date: Wed, 24 Apr 2002 10:08:18 -0400 (EDT) From: CAnet-3-NEWS(a)canarie.ca Subject: [news] The Myth of Five 9's Reliability For more information on this item please visit the CANARIE CA*net 3 Optical Internet program web site at http://www.canet3.net/news/news.html ------------------------------------------- [A good article on the truth about five 9's reliability. Some excerpts - BSA] http://www.bcr.com/forum Deep Six Five-Nines? For much of the 20th century, the U.S. enjoyed the best network money could buy; hands-down, it was the most modern, most ubiquitous and most reliable in the world. And one term--five-nines--came to symbolize the network's robustness, its high availability, its virtual indestructibility. When the goal of five-nines was set, the network was planned, designed and operated by a monopoly, which was guaranteed a return on whatever it invested. It was in the monopoly's interest to make the network as platinum-plated as possible. One of the key points is that "five-nines" has long been somewhat overrated. Five-nines is NOT an inherent capability of circuit-switched, TDM networks. It's a manmade concept, derived from a mathematical equation, which includes some things and leaves out others. It's critical to remember that when you run the performance numbers on ALL the items in a network--those that are included in the five-nines equation and those that aren't--you're probably going to wind up with a number less than 99.999 percent. A well-run network actually delivers something around 99.45 percent. The gap between the rhetoric of five-nines and actual network performance leads to the conclusion that five-nines may not be a realistic or even necessary goal.

Yes, we are peering with UUNet in too many cities a cross USA and all the Network is a messed up, also I found some BGP session cleared by UUNet peering routers. Antonio J.

I live in that area, and its far enough from 111 8th to not cause any serious problems, and there's no other telco or network facilities around there, AFAIK. Most of the fiber, etc, is run along 16th street or up/down 9th ave. Thanks, Matt -- Matthew J.
