DNS Issues, Again

[ Edited ]

Looks like Comcast is having problems with their DNS servers again.  I had to change mine to 4.2.2.2.  I'm in Minnesota.

I'm seeing the same.  Here are the servers which I'm getting from Comcast's DHCP:

 

DNS1: 68.87.72.134
DNS2: 68.87.77.134

 

EDIT: I'm in Chicago.  Just finished chatting with support, they are aware of the issue, but there's no ETA.

Same here in Decatur, IL  I am using Goggles public DNS 8.8.8.8 and 8.8.4.4 and all works fine.

 

We have the same 2 DNS as stated in the message above too.

I'm near Chicago and the DNS is down.  Luckily, I know the OpenDNS IPs and now back.

 

Here's the Comcast DNS status link http://dns.comcast.net/status.php

 

OpenDNS IPs

Preferred DNS server:  208.67.222.222
Alternate DNS server:  208.67.220.220

Re: DNS Issues, Again

I'm business class customer in Michigan, and it seems more like my DNS traffic is being blocked.  I use OpenDNS normally, and I cannot reach it, Google DNS, or DNS for Michigan State University, so it seems like more then just Comcast DNS is not available, at least to me.

Re: DNS Issues, Again

Here is some info from a support chat. I am hoping that the rep is incorrect that this is "This is a system maintenance to further improve our service"

Re: DNS Issues, Again

It is obvious that a few of us network nerds realize what the problem is and have knowledge in our possession as to how to fix it.  I feel bad for everyone else in my city that doesn't know what to do and as stated elsewhere, the trouble number is down too.  What a sounds like "pitch" for these users.

Re: DNS Issues, Again

OpenDNS is working fine. Reboot if needed. I also added the 8.8.8.8 as a tertiary reference, but I ping the OpenDNS server just fine

Re: DNS Issues, Again

Thousands of users to be compensated. I love it! Just be sure to call them with date/time of your outage. 50% off a current bill is the going concession to stay on their service. Still beats U-Verse

Re: DNS Issues, Again

I've tried 3 different DNS servers with primaries and secondaries, and I can't reach any of them from Comcast land, but I know all of them are up as they work fine from where I'm posting.

 

I wonder if any other business class users can reach DNS at all.  The DNS server workaround seems to mostly work for home users it seems like.

Re: DNS Issues, Again

I was on the new dnssec servers 75.75.75.75 and 75.75.76.76 they are also out.

 

Works fine with Open DNS.
