What happened on December 11(12)
by Sean Donelan 19 Dec '01

19 Dec '01

Because several different people have contacted me about this, I wanted to re-check my facts. Last tuesday/wednesday had a few blips affecting connectivity around the net. - Telstra (Australia) had a backbone network routing meltdown disrupting traffic to/from/within Australia for several hours. Timezone, so this happened wednesday in Australia? - AT&T had a fiber cut in Montana - Sprint terminated peering with Conixion (home of Microsoft Windows Update). Conixion restored traffic via other routes later in the day. Before people forward my e-mail again, did I make any gross errors which I should correct?

Catalyst 6500 Sup mods
by Christopher J. Wolff 18 Dec '01

18 Dec '01

Hi group, Just curious whether anyone has had any luck getting Cat 6500 Sup mods to fail-over. I heard the CatIOS is pretty lousy at this task and it's better to go HSRP with the Sup's if you are using MSFC's. Regards, Christopher J. Wolff, VP CIO Broadband Laboratories http://www.bblabs.com

AS 701 local-pref answer.

While >there are many ways to >deterministicly prefer customer routes, local pref >is the most common. AS 701 always announces the best route, as their routers know it. Their average AS-path length is under 2, so it doesn't seem to be a problem. If a customer of AS 701 wants to insure that his/her route is advertised in all cases, s/he could send a community which AS701 edge devices could use to manipulate local-preference upward. [this was covered in a previous posting on this topic] I leave it to your imagination whether peers would be permitted to do this. -David Barak I only speak for myself.

Network Operations Luminaries?
by Pete Kruckenberg 18 Dec '01

18 Dec '01

Though I can name off several 'credentialed' network engineering gurus and the 'bibles' of network engineering, a recent discussion about the source of network operations 'best practices' left me speechless, and curious. Who is/are the network operations equivalents of people like Peter Drucker and Jack Welch--people who are looked at not only has role models for operations success, but as luminaries in the industry for having established and educated the masses about best practices? What would be the network operations equivalents to revered business tomes like "The Practice of Management", "Seven Habits of Highly Successful People", "The G.E. Way" (and a variety of others that populate the shelves of your friendly local executive)? Most network-oriented training seems to focus on the technology, not on operations (and those subtle but ever so critical differences between knowing how something is /supposed/ to work and how it /really/ works, and all of the effort it takes to create a smooth-running operations engine). What are the network operations equivalents to business programs such as Six Sigma? What about something similar to the various leading institutions of business management, institutions that study of how networks are operated (and used), and develop training and methodologies for better operations practices? Pete.

AT&T Broadband

Howdy, Anyone know what's up with AT&T Broadband in Minnesota? They appear to be blocking *everything* from 24/8 to 24/8 that isn't port 25/tcp 110/tcp 80/tcp 443/tcp, or icmp. Everything else is being dropped into a growing black hole.. Thanks, Matthew S. Hallacy

True, but there are precedents (IEEE, Usenix) for technical organizations to provide such services to their memberships.

IP Management software
by Rob Thompson 18 Dec '01

18 Dec '01

Hello, I know the topic of ip space management software has come up before, but it looks like most of the people suggest either free/in-house solutions or QIP and Meta-ip. I was wondering if anyone had any experience with a product called IP Commander by Incognito software? Also, if anyone knows anything about QIP or MetaIP, I would appreciate it if you could respond off-list. I'm looking at all three products to manage our ip address space, and I'd like to talk to someone who's used them in production before. Thanks a lot, Rob

PSI-Net and New York issues????
by Martin Hepworth 17 Dec '01

17 Dec '01

Hi all Our ISP is PSI-Net and we use then in Oxford (UK), LA and New York all on leased lines. Over the past month the service level in NY (West 46th Street, well out of the way of the WTC) has been not up to its usual standard. We've had lousy pings, bad latency for telnet traffic, routing gone wild etc etc. One problem gets sorted and a few days later another is back again. PSI-net indicate that alot of these problems are being caused by local telco problems. Has anyone else seem problems in NY or are we somehow special???? -- Martin Hepworth Senior Systems Administrator Solid State Logic Ltd +44 (0)1865 842300 ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

NAFAIK they are still in Chapter 11 I believe, but they are selling off their country/regional business as franchises and keeping the core backbone as before. Keeps things rolling and they get lump sum cash from the franchisee's to keep cash flow going. -- Martin Hepworth Senior Systems Administrator Solid State Logic Ltd +44 (0)1865 842300 Quibell, Marc wrote: > I thought PSI was going outta business...? > > Marc > > > > > -----Original Message----- > From: Martin Hepworth [mailto:martinh@solid-state-logic.com] > Sent: Monday, December 17, 2001 10:17 AM > To: nanog(a)nanog.org > Subject: PSI-Net and New York issues???? > > > > > > Hi all > > Our ISP is PSI-Net and we use then in Oxford (UK), LA and New York all > on leased lines. > > Over the past month the service level in NY (West 46th Street, well out > of the way of the WTC) has been not up to its usual standard.
