The Frontier website stopped resolving for me, turned out to be comcast DNS.

It was working a day or two ago, so I don't know what happened for them to just "forget" about the site. Switching to google DNS resolved the problem. If you're on comcast and unable to access the frontier forums, switch to 8.8.8.8 and 8.8.4.4 for your DNS to get it working again.

> server 8.8.8.8 Default Server: google-public-dns-a.google.com Address: 8.8.8.8

> www.frontier.co.uk Server: google-public-dns-a.google.com Address: 8.8.8.8

Non-authoritative answer: Name: www.frontier.co.uk Address: 83.222.231.12

> server 75.75.75.75 Default Server: cdns01.comcast.net Address: 75.75.75.75

> www.frontier.co.uk Server: cdns01.comcast.net Address: 75.75.75.75

*** cdns01.comcast.net can't find www.frontier.co.uk: Server failed

I don't think it was Comcast specifically. I run my own DNS server and DNS resolution for all frontier sites starting failing. Something called "domainmonster" was returning bad A record results for frontier. Things were eventually fixed but I had to restart to clear cached results. I suspect Comcast had the bad records cached, possibly longer than they should have.

Honestly, just switch to google's DNS regardless. Comcast DNS just causes problems.

For us tech-slow laymen... I have comcast though I purchased a 3rd party modem and router. How do I do this? Might have to ELI5...

Edit: I'm more of like a tech-dinosaur. Never heard of DNS

DNS is like the Internet's phone book.

You give it the name of the site or service you want and it gives you (your computer) the 'phone number' (ip address) of that site so you can connect.

All DNS services should give the same info, but some update changes and respond quicker than others.

The 'number' for Google's free service is 8.8.8.8 (and 8.8.4.4) which is easy to remember, but there are others.

Your can choose the DNS service you want through the network settings on your computer (unless cable is different to DSL, I only have experience of the later but I'm sure someone will correct me if not)

Google 'set DNS service' and your OS for specific guidance.

Either google or I actually run my network through open DNS. Allows me to have tight control of everything.

Definitely worth switching to Google or OpenDNS (208.67.222.222, 208.67.220.220)

Thanks! I switch to those numbers and forums are up again for me :)

I heard a lot how shitty comcast is, but you should switch from your ISPs DNS server to another one like Google anyway because they're in pretty much all cases super shitty or even filtering stuff out.

I think their hosting company has buggered something up as I cant get to the site using whatever DNS Virgin media provides in the UK.

Ditto BT Infinity.

I did the Google DNS, after thinking it was me or BT for a day or so.

This post saved me, even though I was using a dynamic DNS address.. I was wondering what the issue was. Thanks OP!
