Comcast, Verizon And QWest Peering

May 24, 2008

I find it very interesting that the major ISPs in and around Portland Oregon apparently do not peer with anyone in the region. For low latency you're better off choosing a provider in Seattle or San Jose as traffic always seems to be routed there and back anyways.

Why is this? Is it simply not worth their effort to setup the peering connections because most traffic will be hosted outside the region anyways?

Comcast Peering In California

Jul 14, 2009

Are there any co-location companies in California (preferably northern) that have a peering agreement directly with Comcast?

Not sure if it's peering or transit I should be asking about. Basically I'm trying to get the best path I can afford to Comcast customers in California.

Qwest DSL

Mar 3, 2007

I just switched to Qwest DSL for internet access and I have one problem. I cannot access any sites hosted by ServerWizards on all 5 pcs in my house. Even people who comes to my house with their laptop cannot access my sites hosted with SW. Qwest technical support can't help.

This problem occured three times so far this month

1st time I assigned a dedicated IP on all pcs to make it work
2nd time I contacted Qwest support and rebooted the modem to make it work
3rd time I contacted support again and tried everything but does not work

I have no Firewall other than Windows forewall. No virus to think of. Reboot

troubleshoot this or explain what the problem might be.

Internap / More Peering Better

Jan 26, 2008

My colo is charging about $80/Mbit, they use InterNAP. Is that reasonable? This is in west coast/california.

That brings me to my other question, how do you know whats a good network? How is hurricane electric compared to InterNAP?

fixedorbit.com shows HE on the top 10 list and shows a lot of peering. I don't see InterNAP on that list at all! Does that mean thats it not as good?

The more peering, the better? (I guess we assume that the network provider isn't over selling and isn't cramming a lot of customers into a single port etc...)

This location would be a Verizon central office. Anyone know of a good Verizon sales representative or reseller?

Business Of Peering

Jan 14, 2007

How does peering work from the business angle? Say company X has bought a Gb port at an exchange, and wants to peer with other folks peering there. What are the folks typically going to expect from X before they'll peer with it? What are the
characteristics of X that would make folks willing/unwilling to peer? I've no idea what the relative importance of things would becontent (desirable, undesirable) WAN Network. (Does one have to have one?) technical cluefulnessBrand Qualities of the potential peer. It's hard to figure out the realpolitik of it all just by understanding the tech (BGP, etc.) and http://en.wikipedia.org/wiki/Peering .

Network Providers In Verizon CO's

Jan 22, 2008

If one was interested in becoming a CLEC and hosting their own gear inside a central office, how do they find out what providers are available and on-net in central offices? Is there any database to look at?

I asked my Verizon sales representative and she stated that she couldn't tell me what customers were in their CO for privacy reasons. That is understandable, but how do I find out who is in a CO and who I can cross connect with? You are not forced to buy internet access only from the ILEC (Verizon) are you?

Qwest Texas Network Experiences

Jun 5, 2007

Can anyone comment on how their experience has been with the Qwest network in the Texas region? It seems by looking at their network map that they have many directly links to other cities coming out of Houston which is a surprise to me as everything seems to come from Dallas on other networks.

Can anyone comment on pricing? What can you get a FE or GE commit from Qwest for?

Route From Level 3 To Qwest On The West Coast

Aug 30, 2009

I am looking at getting some Qwest bandwidth at 200 Paul, San Francisco. Not being too familar with Qwest's network and as part of evaluating that decision I did some testing to see how the routes/latency looked from various points on the Internet and from our other data centers. For pretty much all the testing I did from the major tier 1/2 networks, Qwest has great peering in places you would expect resulting is decent routes and low latency.

The strange thing is that the one exception is routes from Level 3. As an example, traffic from various Northern California points on Level 3's network to a test IP on Qwest's network in Sunnyvale all go via Denver to connect to Qwest and then back to the Bay Area. For LA originating traffic, it goves via Dallas. Same thing for Seattle that is going via Denver.

Hard to imagine these two tier 1 providers don't peer at any location on the west coast at all? Is this typical between these two or is there some temporary outage right now? Or is there some peering spat going on between them?

Seems pretty silly for traffic to go 3,000 miles between points that are only 10 miles apart!

Here is an example of the route to a test IP sunnyvale.speedtest.qwest.net (205.171.214.185):

1 vlan89.csw3.SanJose1.Level3.net (4.68.18.190) 0 msec

For years we have been able to send and receive through our web sites using Qwest and then a few weeks ago it stopped working for sending completely. I checked the usual things like port 25; I changed the outbound mail address to smtp.live.com per their instructions. Nothing. Now that Qwest is MSN it just doesn't work and their offshore "support" is worthless. This happens using Windows XP Pro and Vista.

Comcast PRO And RDNS

May 7, 2008

I have Comcast Business PRO Internet service for work purposes. I've got two web/dns servers and two mail servers, each having their own IP. These are all fine.

There had been a couple situations in the past where I would receive a "Relaying Denied" message from my PINE when sending mail out. At examination of the maillog, It's essentially telling me that these messages are being generated because of the lack of reverse DNS.

xxx.xxx.xxx.xxx-Oregon.hfc.comcastbusiness.net., instead of my.domain.com.

I did a couple searches on Google, and read somewhere that Comcast is unwilling to create rDNS entries, but they've not specified, so far, whether they subscribe to PRO or residential service.

Before I spend 90 minutes on the phone with Comcast, I thought I'd see if anybody here has been successful with rDNS and Comcast PRO before. It seems to me that by denying this, it defeats the purpose of the "dedicated" service that I signed up with ...

FDC Network Upgrades - Comcast Etc

Jul 1, 2008

it looks like FDC is taking more pain than usual in terms of network upgrade, i see the network seems unstable till 5am and even now the sessions are getting lost, once in a while like once a hr, anyway this is not the reason i am writing this, but when did comcast become transit provider, i did a trace to UK for example and i see trace going through comcast and then hopping onto tiscali/level3, it looks to me like, comcast could be trying to even out (1:1) it;s carriers so that they get all inbound for free sort of and it;s upstream selling as a transit make money there. sort of, just a surprise to me at this point

Emails Getting Blocked By Comcast/Trend Micro

Apr 15, 2009

I've recently gotten a new dedicated server and am in a bit of a bind because all emails to Comcast are blocked. I have verified that the IP is not on any RBL I can find but it does appear on the Trend Micro DUL list. This is a list that appears to not be maintained but which the wingnuts at Comcast are using. Emails to the maintainer of the list or to Comcast are auto-responded to and promptly ignored.

I'm at wits end (admittedly, not a long journey) with this. As a small provider I guess I just don't count but it is annoying as hell that there is no way to get these folks to listen. Every legitimate RBL on the planet has someone to help with issues but Trend Micro appears to not. And Comcast doesn't care about their customers getting legitimate email. Actually, I guess they just don't care period.

Has anyone else experienced this and, if so, were you able to figure out what magical incantation it takes to get through to a human who cares?
