Over the last several months I encounter sporadic failure with Snaps DNS servers on my VDSL connect.

I'm nearly positive that it is Snap as I can always bounce to my VPN connection or manually reset my client DNS to Google's servers and instantly resolve the problem.

It's a short term failure though. Usually anywhere from 1-10 minutes and then it begins working.

I have reported this to Snap several times and they always say that everything is fine and they have no problems, but I'd like to hear from other users.

I never trust the ISPs DNS servers. Very few do a good job with it. I use OpenDNS which I have been very happy with. You can set it up on your router and it just works. :)

Only problem with that is you won't get optimal CDN DNS resolutions (especially for Akamai, Google/Youtube)

Yeah, I feel that DNS should be reliably handled by your ISP and my experience is that overall performance is far better using your ISPs DNS than an external/public DNS (presuming the ISPs DNS is actually working). I've run DNS benchmarking tests on SNAP and it's better than Google...when it works.

Only remember having problems with Snap DNS once or twice over many years. Have you tried setting it on your computer directly, rather than it proxying it through your router?
Or skip one of them and add their tertiary server 101.3

Haven't noticed any problem. Can you put in Google DNS or similar as your third DNS server? That way if Snap DNS is down you can fallback to something that's probably got many redundant servers around the planet.

Is doesn't always work that well, Windows OSs do a crap job at failing over to a second or third DNS server in a short space of time.
