DNS server problem

I'm just wondering if anyone else has this problem.
At random times (usually once or twice a day, usually for about 5 minutes) I find that I cannot get a response from the DNS server.
Any other activities that are in progress carry on quite happily and I can access web pages provided that Opera does not need to use DNS for (i.e. reloads or child-pages) but all new web page requests or those where Opera decides to redo the DNS lookup, fail.
I've only raised one tiket on this when the problem lasted for a much longer period but the only response I got back was a cut and paste: "I can confirm that ... are operating correctly" (or words to that effect).
Well, they would be, wouldn't they? Otherwise how would I have raised the ticket?
I really don't see how this can be anything at my end otherwise why is it just DNS lookup that fails?
Does anyone else get this?

Re: DNS server problem

Which DNS servers are you using? When this problem occurs what results do you get when trying to ping bbc.co.uk and then ping 212.58.224.131

Re: DNS server problem

I too have seen the odd intermittent DNS failures, usually at busy times, which is why I switched to OpenDNS.

The setting for DNS servers is "get DNS server automatically".
I'll check the pings next time it happens but I'll lay money that the 'bbc' address will fail and the dotted quad will succeed.

Thanks for reminding me about OpenDNS.
I've switched to that now. Let's hope that makes the problem go away.
I don't think my problem was limited to busy times. When it failed it failed solidly but when it came back there were no delays or intermittant 'hangs'.

Re: DNS server problem

TBH I tend to have one of our DNS addresses as the primary server and an OpenDNS as the secondary. I'd be interested to know if you continue to get these type of issues.

I'll make a note and post in a couple of weeks if the problem doesn't recur.
It seems to have been a lot worse recently so that should be long enough.
If it does recur I'll be posting sooner.  Smiley
