Time warner dns issues

[ Edited ]

Over the past week, I've had the worst browsing experience of my life and I couldn't quite pinpoint the reason until I noticed it when viewing uniqe websites.

 

I'd call support but they are of no use to me and gaze into the phone when I mention something other then a modem reboot.

 

[root@localhost ~]# dig themotorcycleschool.com

Oh look, it could be reached now.  But why are your dns servers timing me out.   Are you rate limiting me or are your DNS admins taking a nap?

 

 

Tried logging into your forums to complain but I couldn't even load your sso login until a few tries :

 

http://oi41.tinypic.com/i4h3j4.jpg

 

why is this? Because I could not resolve your domain :

 

[root@localhost ~]# mtr ids.rr.com
^C
[root@localhost ~]# dig ids.rr.com

 

mtr timed out as well until I gave it a keyboard interupt, then ran a dig where it completed in 86 ms.

 

I've never had this issue and it seems I don't have connectivity issues over ipv4 and only when using DNS to resolve a host.

Re: Time warner dns issues

So I left an mtr running on youtube for an hour and I tested using google's resolvers, guess I didn't see the loss earlier but now I'm seeing it when running mtr's for a long period of time I'm starting to capture the loss.

 

 

Here is a 500 count mtr to show icmp echo request loss.

 

[root@localhost ~]# mtr -w -c 500 youtube.com

[root@localhost ~]#

 

Wanted to follow up, as I'm putting more time into this, the issue is not the DNS resolvers. It's the packet loss I'm seeing.

So I guess I have packet loss and dns issues? Note 8.8.8.8 (Google public DNS)

Re: Time warner dns issues

I am seeing issues also!!  I am running traceroutes and continuous pings.  Pings are randomly dropping packets and traceroute is timing out at different times.  One of my ping tests is to 8.8.8.8 so there is no DNS involved in an IP ping.  

 

This has been happening to me for 3 days now.  I get random traceroutes that have issues, see below.  It's very interesting like a port is flapping or a device is overloaded.  I would think by now TWC would have figured it out.

Re: Time warner dns issues

Whois for owners and locations of your problem servers.

ae0.pr1.dfw10.tbone.rr.com - TWC Newton, KS
74.125.48.65 - Google Mountain View, CA
72.14.233.65 - Google Mountain View, CA

If the Whois locations are actual and not just office locations, I can understand the loss between RR in KS and the Google gateway in CA because of the distance.

The loss between the two Google units is harder to explain.

Not sure if it would do any good, but you might e-mail the results of you tests to tech support at both TWC and Google.

na man, I have problems with all sites, I figured if I was gonna test I might as well use a reputable datacenter such as google.  My loss always seems to however around ae0.pr1.dfw10.tbone.rr.com. And I'm sure this is what's causing my DNS issues too from dropped udp packets.

Having already moved away from TW's under-resourced DNS servers, I was still having horrible connectivity. While I'd love to jump on the bandwagon, It seems to have abated today (2:00 AM).

Re: Time warner dns issues

There's more than a DNS problem in my area of Queens. I'm getting packet loss and latency in the 2s range while pinging my gateway!

You should try to play World of Tanks. Time warner chaged something about a month ago. and totally nerfed my connection , made the game useless. My download speed does not exceed 2mbps now.

Re: Time warner dns issues

I have had major issues recently with 209.18.47.61 and 209.18.47.62 DNS servers from TWC.

I called T3 about it to let them know about the issue but they had no idea about any issues, which was no surprise.

I had a lot of time out issues as reported by others and then I switched to OpenDNS servers and that resolved all my issues.
