UK DNS Getting Less Reliable?
More and more intermittent errors

I have been seeing a steady increase in the number of intermittent DNS errors recently, with many of our clients also getting the errors.

This doesn't seem to be associated with any particular DNS servers as we have tried 3 or 4 different servers.

Is anyone else experiencing the same phenomenon?

yes, it sort of looks like certain routes don't work for a while.

e.g. site-a can't be accessed by user-1, but user-2 and user-3 have no problem with site-a.

Meanwhile, at the same time, user-1 can access site-b and site-c

Half an hour later it's all OK again.

All very odd.

Yes I have had a case of a client who could access site A on IP address 1 and not site b on IP address 2 where IP addresses 1 & 2 are on the same network using the same router.

It has to be some kind of strange problem with DNS.

I have had problems this morning trying to access sites that are definately up and running, they just will not load up. Both sites are hosted in the Oxford area and I am based in Manchester. Do you think this is the same problem?

I'm seeing this, too (not the snow).

I'm also seeing gateway timeout more often.

The real question now becomes is there anyway we can address this problem?

Things have got so bad for us in the office I've switched us to an internal DNS service which forwards requests to our external servers dotted around the UK and USA. This is proving more stable, though we are still having the occasional problem.

What service provider/DNS are people using? We're using BT here, and I'm using NTL at home, (based in the UK), using the DNS servers of the ISP. The office connection was having more noticable problems than I found at home.

BT was the problem for us. NTL didn't have any noticable problems, either did freenetname.

These are the only ones we have tested. Any ideas on a solution yet?

When I phoned BT to inquire in the first instance I was asked by a person on their broadband help desk to "explain what I meant by a DNS lookup" Hurrumph!
