Register.com .....routing issue?
by Los, Ralph 06 Sep '01

Hey folks, Has anyone tried to trace to Register.com's main page yet? I haven't been able to hit it, and when I try to trace down to them I end up hitting a 10.0.30.x network, then go back to public IP's...how is that possible? Anyone else having trouble connecting to them? Happy Monday! (still) Ralph M. Los Asst.

Number of cable cuts is down
by Sean Donelan 06 Sep '01

06 Sep '01

The ATIS Network Reliability Steering Committee met last week to review last quarters network outages. I haven't seen what they've come up with, but last quarter they noted a decreas in facility outages. I also noticed an interesting change in Internet-related outages. The number of cables cuts is down since January 1 2001 compared with the same time period in 2000 and 1999. Previously, one of the primary causes of Internet cable cuts was other carriers' subcontractors installing new fiber in the same right of ways. Most high-bandwidth Internet-carriers seem to use the same right of ways, which aren't identical to the LEC voice infrastructure. For example, the Baltimore tunnel fire had little impact on voice calls, i.e. no carrier filed an FCC outage report, but the fire's impact showed up on Internet traffic. With the change in economic climate, many cable projects have been stopped. My guess is less carrier work in the same right of ways means fewer cable cuts. The number of farmers burying a cow, and gophers chewing on cable is the same. There is a silver lining on every cloud.... Those carriers which have fiber into the ground, are less likely to have cable cuts now.

RE: ATM failure - No the other kind of ATM

Folk, The story I read referred to a software glitch resulting from unusually high volume over the Labor Day weekend. Most ATMs use OS2 (stand around one until the maintenance person re-boots it). My WAG (wild a** guess) is a fixed length field somewhere, say X,XXX,XXX, and the network had 10,000,000 whatevers over the Labor Day holiday that was then repeated when it came back up due to the pent-up demand from the system being off line. When was the last time you took a look at any data that increments in fixed length fields? Your mileage may vary. -Al -----Original Message----- From: Sean Donelan [mailto:sean@donelan.com] Sent: Wednesday, September 05, 2001 1:11 PM To: nanog(a)merit.edu Subject: ATM failure - No the other kind of ATM As most US residents are aware, the Citibank ATM/Automatic Teller Machine network failed last night. Citibank is still having problems today. >From Reuters: "The Citibank ATM network and other systems experienced a temporary outage last evening." "While our systems were restored by early Wednesday morning, we have continued to experience difficulties this morning. We're working hard to resolve the issues as quickly as possible." Since there is very little "unique" network equipment in the world now, just about everyone buys equipment from the same vendors. So the question is, Can we learn anything from Citibank's experience. Is there anything about their continuing problems which may be used to improve general network reliability? I tried to find out some information from Citibank's web site about the issue, but I didn't see anything.

I'm going to guess the latter, but >thought I'd ask... Ahhhhhhhhhhh, important distinction. Sorry it was not clear. These were all over private lines, modems or private FR. When I said "IP", I meant they just used IP as a transport protocol. (As opposed to raw SNA or something.) I have never set up an ATM that used the Internet. -- TTFN, patrick

[] > [] In my experience, banking ATM networks tend to use pretty odd equipment. Most ATM networks tend to be leased lines or use FRADs that speak the teller machine lingo. Some banks use boxes that encapsulate the protocol in TCP, so I guess that a failure there could be a big problem. --Chris

FW: wackamole 1.0

We interupt the normal NANOG threads for this potentially interesting item. % ------------------------- % % Hi, % % We at the Center for Networking and Distributed Systems at Johns Hopkins % University % (http://www.cnds.jhu.edu) are happy to announce the release of Wackamole, % a software tool that provides N-Way Fail Over for IP Addresses in a cluster. % It is available here: http://www.backhand.org/wackamole/ and is released % under the CNDS open source license % http://www.backhand.org/wackamole/LICENSE.shtml % which is essentially a version of BSD license with a somewhat stronger % advertising % requirement. % % Wackamole is a tool that helps with making a cluster highly available. % It manages a bunch of virtual IPs that should be available to the outside % world at all times. Wackamole ensures that exactly one machine within the % cluster is % listening on each virtual IP address that Wackamole manages. % If it discovers that particular machines within the cluster are not alive, % it will % almost immediately ensure that other machines acquire the virtual IP % addresses the % down machines were managing. At no time will more than one connected machine % be % responsible for any virtual IP. % % Wackamole also works toward achieving a balanced distribution of the public % IPs % within the cluster it manages. % % How it works: % Wackamole runs as root on each of the cluster's machines. It uses the % membership % notifications provided by the Spread Toolkit (http://www.spread.org, also % available % under a similar license) to generate a consistent state that is agreed upon % among % all of the connected Wackamole instances. % Wackamole uses this knowledge to ensure that all of the public IP addresses % served % by the cluster will be covered by exactly one Wackamole instance. % % Wackamole is the newest component in the Backhand project % (http://www.backhand.org) % adding to its predecessors mod_backhand and mod_log_spread. % % For questions or comments - e-mail wackamole(a)backhand.org % % Best regards, % % :) Yair. http://www.cnds.jhu.edu -- --bill
