Carrier Hotels in Chicago
by Robert Boyle 29 Dec '07

29 Dec '07

Hello all, I located our new midwest datacenter site, but I'm going to need connectivity to Chicago. At which other middle of the country places should we connect? We will obviously connect back to our network in New York and Los Angeles, but I'm not familiar with other carrier hotels or IXs in the middle of the US. What is in Dallas? Does anyone have any strong feelings about Telx in <http://www.telx.com/facilities.php?section=ChicagoIL350ECermakRoad>Chicago, IL @ 350 E. Cermak Road or <http://www.telx.com/facilities.php?section=ChicagoIL600_780SFederalSt>600 S. Federal Street? Are those the best places in the midwest? Any other suggestions? I am asking here because I am looking for a carrier and ISP perspective. I am going to colocate core and edge routers and I need connectivity to a large pool of carriers and no MRC on cross connections. Any help or advice would be appreciated.

That is a Terremark facility, but lots of carriers are there. Look at their carrier customer list and you will see all of the carriers connected to them in Miami: http://marketplace.terremark.com/bysegment.asp?s=1 We have a few connections which go through NOA and we have found the pricing to get high speed circuits to NY and LA from Miami to be very reasonable. Good luck with your project. -Robert Tellurian Networks - Global Hosting Solutions Since 1995 http://www.tellurian.com | 888-TELLURIAN | 973-300-9211 "Well done is better than well said." - Benjamin Franklin

South America Peering
by AD 28 Dec '07

28 Dec '07

hello, does anyone have any experience with peering in S. America? I am looking to move a lot of data between NewYork/LA and a few south american countries and looking for some ISPs that have reliable peering into those countries. Any recommendations would be appreciated. The one i did find was Terremark, but no others yet. thanks Adam

IPv6 Addressing Plans
by michael.dillon＠bt.com 28 Dec '07

28 Dec '07

During all this discussion about v6 and home networks, has anyone had a look at ARIN's IPv6 wiki, in particular at the IPv6 Addressing Plans page? http://www.getipv6.info/index.php/IPv6_Addressing_Plans Although it still has the original note about being a bit of a strawman proposal it has incorporated a lot of input from earlier discussions on the NANOG list and the IETF list. Item 12 on that page applies directly to home networks: 12. All customers get one /48 unless they can show that they need more than 65k subnets. -Host count is irrelevant. -Do not assign from PoP aggregates -Carry customer networks in iBGP -Aggregate only in eBGP -If you have lots of consumer customers you may want to assign /56s to private residence sites. Aside from snarky remarks about the IETF, does anyone have anything substantial to contribute that isn't already on that page? If you want to you can use the "discussion" tab on the wiki to comment. --Michael Dillon
