Re: Qwest Utah fiber cut

I was hoping someone might be able to shed some light on the Utah cut. The news report said that the cut happened near Monroe Utah, which is several miles off of I 70. Yet the cities that were reported effected included St. George, Cedar City, and Salt Lake, which all are adjacent to I 15. The puzzling part is that in our "best effort" database Qwest does not have long haul fiber running down I 70, but it does have a lot of fiber running down I 15. There is Qwest fiber on I 15, all the cities affected are on I 15 yet the reported cut was near Monroe off of I 70. I'm not familiar with Utah geogrpahy and this comes simply from looking at our maps. Just trying to sort out the seeming discrepency. Any insight? ----- Original Message ----- From: Sean Donelan <sean(a)donelan.com> Date: Friday, May 21, 2004 11:14 am Subject: Qwest Utah fiber cut > > http://www.thespectrum.com/news/stories/20040521/localnews/471985.html > > Businesses feel effects of communications outage > By RACHEL OLSEN > rolsen(a)thespectrum.com > ST.

I would agree that most Telco's put the initial ring fiber pairs in the same conduit due to cost savings and build out permits; but sometimes the issue is not cost; but laziness on the part of the company or the engineer. In the past I worked for a company that designed and installed MAN rings and more often then not the company would work a ring into a single conduit just because it was easier to do.

Why the heck would a fiber > this important not be? sonet, obviously, does not *have* to be in a ring, but it often is. unfortunately, a fair percentage of the time, the additional protection offered by a ring topology is a mirage, due to a configuration known as "collapsed backbone". in this instance, both pairs of fiber ride in the same conduit for some portion of the distance (most notably laterals to building entrances, but sometimes for a fair distance down the street). the driving factor in building this way is usually cost savings. while this arrangement does protect against failures of optics and electronics (which in fairness are indeed more common than fiber cuts), it provides no protection against hungry construction (or in this case, lawn maintenance) equipment. ---rob

This is from a previous thread on the topic of fiber cuts but I thought it fit this discussion well, epsecially since it concerns Verizon. Apologize for not being able to recall who originally posted it - only have the citation. In an August 5th, 2003 court case involving the Maine Public Utility Commission an expert witness from Verizon stated that only 10% of the fiber rings in Maine are fully redundant, and 90% are at least partially collapsed and vulnerable to single cut failures (Maine PUC, 2003) Maine PUC, 2003, “Docket Number 2002243” http://www.state.me.us/mpuc/misctranscripts/2002-243%20080503.htm Appears it should not be a suprise at all it was not redundant. On a related note another researcher at GMU has collected all the outage reports that "were" posted on the FCC website and put them in a database form, and we are going to try and run correlations between outage location and the density of fiber located there. ----- Original Message ----- From: Joe Abley <jabley(a)isc.org> Date: Friday, May 21, 2004 10:23 am Subject: Re: fiber cut 19 May/PM -> 20 May/AM in Ashburn, VA (lawnmower?!) > > > On 21 May 2004, at 08:09, Robert E.

RE: Dell power connect switches.
by Joel Perez 21 May '04

21 May '04

Wow, I got more responses than I thought. I tend to agree with the majority of the opinions. I tested a 3048,3348 and 6024 in our lab. We will be creating about 12 VLANS total. While that isn't a lot per say, the 3048 couldn't handle more than one VLAN on it. The 3348 let us add several vlan's but then I couldn't trunk them together.. The 6024 we really didn't experience any problems with so far. But, I don't want some of the switches to work correctly some of the time. I am going to make my stand against buying these for our network and try to pitch Cisco for L3 stuff and RiverStone for L2 stuff. I know some people don't like RiverStone, but I have several years of experience with them at my previous place of employment. I agree that for L3 they aren't worth it, but for L2 I never had any issues. Well... worms love to melt RiverStones, but that is another story. Another thing that bugs me is that the existing Dell switches have had ports go bad on them. At least with the RiverStones I can replace the Ethernet cards. With the Dell's I have to replace the whole switch. Thanks again to everyone! ------------------------------------- Joel Perez | Network Engineer jperez(a)uspgi.com | www.USPGI.com ------------------------------------- -----Original Message----- From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of Joel Perez Sent: Thursday, May 20, 2004 4:11 PM To: nanog(a)merit.edu Subject: Dell power connect switches. Good afternoon, We are planning to deploy several Dell PowerConnect 3324, 3348 and 6024 switches on our network. We currently have between 200-300 users and servers that these switches will service. We are also planning to add about 300-400 more users in the next 2-3 mos. 85% of the users are for our call center where they all use Terminal clients and connect to W2K TS.

I originally proposed using RiverStone as L2 switches but price was a factor in our decision to go with Dell. That is my main concern at this point. The Dell switches are very cheap compared to other L2 switches out there. Will this be a case of "you get what you pay for" or are they really good performing units?

fiber cut 19 May/PM -> 20 May/AM in Ashburn, VA (lawnmower?!)
by Robert E. Seastrom 21 May '04

21 May '04

Since none of the usual suspects have noted it, I'll give a cursory nod to an ILEC (Verizon) fiber cut that happened mid-afternoon yesterday in Ashburn, VA. About a thousand POTS customers were down (including several OOB dialups of which I am aware in the Equinix facility in Ashburn), as well as some T1 and faster loops to Equinix and elsewhere in the immediate area. Outage was likely off the radar because despite the big concentration of connectivity in the affected area, the natural cost disadvantage of the ILEC meant that few circuits of consequence were riding that fiber. Service was resumed after approximately 12 hours. RFO given was that the fiber cut was caused by a commercial lawnmower. Humorous comments left as an exercise to the reader. ---Rob

I'm in Telecity at 8/9 Harbour exchange and I lost 2 BGP sessions to Abovenet at about 10:50 BDT. I've been told there is a power failure there but I'm not sure if my problem is related.

> you ask do folk run ntpd on every server. And the answer is, yes, on all Unix servers. Have done so for many years. Running ntpdate from cron was always regarded as a poor substitute. > i wonder if folk run ntpd on every router. i did and do. Yup. Or sntp if that's the only thing available.
