Anyone else getting excruciatingly slow DNS lookups using TCL servers at the moment?

It's getting so bad I'm considering firing up my trusty old Linux box to be a dnscache client, and just talk directly to the root servers again.

I don't understand how it can be this slow, unless they're using Windows or BIND (ugh).

Any TCL techies reading this forum, please check out http://cr.yp.to/djbdns/dnscache.html :)

Fast, tiny, leaks no memory.

I've noticed it hasn't been great the last few weeks, so I too have switched to a little eeepc I have running as a server. It's now doing the DNS lookups and caching for us. Things seem a bit faster now.

Using third party DNS providers is not a good idea, as it will have problems if your destinations uses CDN and provides responses from IP addresses different from what your network is expecting.

So what would you suggest to use instead of OpenDNS for a group of about 8 childcare centres that need to block objectionable sites on the internet?
Bearing in mind that OpenDNS costs them nothing.

Opinions are my own and not the views of my employer.

In this case I'd say the childcare is not too interested in things like Facebook, right? Then go for OpenDNS.
