RE: L3 East cost maint / fiber 05FEB2012 maintenance

We saw the same here, However our session did tear down. I was told they were doing scheduled "emergency" maintenance about 3:30PM EST Yesterday. We're hung off the orlando market.

List of Comcast speeds in Chicago, IL (North side near I-94: Addisson/Irving Park/ area)
by Ishmael Rufus 05 Feb '13

05 Feb '13

Could someone help verify the listed speeds for the different services for Comcast: Performance - 20mbps (Customer support is claiming it's now 15mbps) Blast - 30 mbps (Customer support is claiming it's now 20 mbps) I was getting 20+ download speed tests on Performance which is correct. When I told customer support I was getting half (because of packet loss) they brought this other information to my attention

2013.02.04 NANOG57 day 1 afternoon notes

Notes from the afternoon session, including the community meeting, but minus most of the BCOP presentation have been posted: http://kestrel3.netflight.com/2013.02.04-NANOG57-day1-afternoon-session.txt it looks like apache2 serves up about 100 connections, then wedges. :( No time to troubleshoot it, but i'll try to check back once an hour and kick it in the head. Thank you Dave, our hero of the day for making sure the WCIT talk contents did *not* get sealed behind closed doors! round two begins tomorrow morning, bright and early. ^_^ Matt

Is Google Fiber a model for Municipal Networks?
by Leo Bicknell 04 Feb '13

04 Feb '13

I've been searching for a few days on information about Google Fiber's Kansas City deployment. While I wouldn't call Google secretive in this particular case, they haven't been very outgoing on some of the technologies. Based on the equipment they have deployed there is speculation they are doing both GPON and active thernet (point2point). I found this presentation: http://static.googleusercontent.com/external_content/untrusted_dlcp/researc… It has a very good summary of the tradeoffs we've been discussing regarding home run fibers with active ethernet compared with GPON, including costs of the eletronics compared to trenching, the space required in the CO, and many of the other issues we've touched on so far. Here's an article with some economics from several different deployments: http://fastnetnews.com/fiber-news/175-d/4835-fiber-economics-quick-and-dirty Looks like $500-$700 in capex per residence is the current gold standard. Note that the major factor is the take rate; if there are two providers doing FTTH they are both going to max at about a 50% take rate. By having one provider, a 70-80% take rate can be driven. Even with us a 4%, 10 year government bond, a muni network could finance out a $700/prem build for $7.09 per month! Add in some overhead and there's no reason a muni-network couldn't lease FTTH on a cost recovery bases to all takers for $10-$12 a month (no Internet or other services included). Anyone know of more info about the Google Fiber deployment? -- Leo Bicknell - bicknell(a)ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/

RE: Global caches
by Kyle Camilleri 04 Feb '13

04 Feb '13

Hi Alex, We already have Google Cache although we don't peer with them directly. As said earlier, what I'm after is to cache content to provide better performance to our customers and alleviating some bandwidth towards provider. Taking an example of Global Google Cache, they provide and manage the servers themselves, absolutely no huge effort needed from the ISP. Making it very convenient. I know of Akamai and Netfix that does this in a fairly similar way, but would like to know if there are any other CDNs that do this. Regards, Kyle From: askoorb(a)gmail.com [mailto:askoorb@gmail.com] On Behalf Of Alex Brooks Sent: 04 February 2013 16:13 To: Kyle Camilleri Subject: Re: Global caches Hi, On Mon, Feb 4, 2013 at 2:03 PM, Kyle Camilleri <Kyle.Camilleri(a)melitaplc.com<mailto:Kyle.Camilleri@melitaplc.com>> wrote: Dear Nanog Community, Some CDN providers such as Akamai and Google (often called Global Google Cache) are offering caches to ISPs. It is very convenient for small ISPs to alleviate bandwidth towards the provider, but also the CDN provider benefits by putting source of data closer to the user resulting in far better performance. Does anybody know of any other CDN providers that offer similar caches? I think I should give a note of caution first. Normally, CDNs will only consider you for caching if you already peer with them - in most cases the majority of any performance or cost improvements come from direct peering with a CDN first. Unfortunately, I can't find an entry for you on PeeringDB, but assuming that you are AS12709, you only seem to be peering with a few 'major' networks (Vodafone Malta (AS33874) WIND Italy (AS1267), Global Crossing (AS3549) and Level3 (AS3356)). If you don't (or can't) peer with, say, Google or Akamai, they are unlikely to invite you to join their caching systems. I'm guessing that because you are on an Island in the middle of the Mediterranean; with nobody wanting to peer on the Island, you are looking to cache as much as possible on the Island, as undersea cables are expensive. Is this correct? If you give the list a bit more information about what the problem you are trying to solve is, the people here are pretty good at coming up with solutions or putting you in contact with people who may be able to help. Best wishes, Alex

Announcing a reserved ASN?
by Suresh Ramasubramanian 03 Feb '13

03 Feb '13

AS23456 is currently announcing a good few netblocks (which don't have a very good smtp reputation, by the way). Funny thing is, that's a special use ASN as per rfc4893, something about two octet ASNs that don't have a four octet representation. Only one upstream (airtelbroadband-as-ap, as24560) that I can see > > 103.7.204.0/22 > > 103.14.208.0/22 > > 103.23.124.0/22 > > 103.30.12.0/22 > > 103.245.112.0/22 > > 111.235.148.0/22 > > 177.55.249.0/24 > > 186.251.192.0/21 --srs (htc one x)
