Nameserver problems?

I can ssh into my development server (hosted elsewhere) and use links to access it, so it appears it may be a problem with the nameserver of the ISP my parents use??

None of my linode hosts are resolving, but other hosts are.

Yup, changed my nameserver to 8.8.8.8 (google public) and it all works dandy, so this must be an issue with whatever DNS is assigned by my parents wireless router.

Bugs the hell out of me though, does that mean my site can not be accessed from time to time from people who use opendns, while other sites can?

Looks good from here:

You'll have to ask OpenDNS what the problem is. Linode's nameservers have been extremely reliable in my experience. Looks like OpenDNS is resolving properly now:

This also happens to me quite often when using OpenDNS. If you are quick enough and click on the detailed error link, it will say that one or more of the Linode DNS servers had a SERVFAIL error.

This has been happening for a few months now. I've simply ignored the error and just re-entered the URL to get around the OpenDNS error. Simply refreshing the page does not work due to the OpenDNS URL redirection 'feature'.

I've also been having this problem. It's very strange as I'm sharing a linode with multiple sites and randomly only one may not work suddenly for awhile.

For example, I'm using OpenDNS servers (and so are millions of potential visitors) and today (4/4/11) creativeculturemedia.com won't come up, but spiritlakepublishing.com will, and they are on the same servers, same domain servers, nothing is different, but one work and the other doesn't.

Does anyone know what can be done? I tried the refreshcache at opendns.com to no avail. Thanks.

Ask people why the hell they're using opendns' known to be unreliable servers?

Since when is OpenDNS unreliable? Or are you just referring to this?

I've been using OpenDNS for well over a year and have had no problems at all.

So far, every link I click on when searching google for "opendns unreliable" claims just the opposite….

personal experience with lots of similar problems like this one led me to dump it and go with google whenever I hit wonky DNS in various hotspots (which happens way more often than you'd think)
