Has anyone else noticed a massive increase in the last 4 months or so
of DNS lookup failures? Is this a net-wide phenomenon or limited to
one or 2 isps? (Virgin.net/NTL/Whatever they're called this week in my
case.)

I have even had confirmation - unofficially - that it's causing my
isp's tech support personnel issues too. DNS is fundamental to the way
we use the internet, if the isp can't even get that right, what hope
is there?

What are you using?

BIND 9.

Works as a caching-only nameserver OOTB, and you can poison (e.g.)
Google, Altavista, etc. if you want to as well

Not much point unless other people use it as well, though...

Yes, I've used it, but I kept getting a general error with the .exe at
start-up, so I dumped it.
Looking for a Windows soft alternative as I have no intention of going down
the *nix or hardware route.

Anything beyond that is out of my scope, unfortunately

Last time I used it, it was. If the errors continue I might have to
dig out the installer again.

Can I ask how you provide your own DNS?

offer this service for a small fee, a few offer it for free, or you can
cheat and try giving it the same address twice).

Then you install BIND and set up the appropriate zone files for the
subdomains, etc. that you want.

In all, it's a bit of a pain . Google is your friend.

Or you could look at a simple solution like treewalk

For most of the domain name...ask my ISP to let me use my own DNS for
the domain names they register for me, and give them the IP addresses of
my name servers. For one of them, go to the country registrar's control
panels and do it myself.

Configure and start up the copy of BIND that comes with my operating
system. Do this for the backup server too.

There's a couple of optional things, but that's basically it.

There are ongoing issues with NTL proxies. It's rarely a DNS failure with them
as such.
Changing the proxy can help and this gives you all the gumph:

No, wrong tree :-)

This is most definitely a DNS issue - I've spent a /long/ time analysing
DNS queries and the corresponding replies. There are a couple of threads
around on the subject - the gist is that DNS replies from various
servers are correctly formatted and have good checksums; they just
happen to have had the answers stripped out. The only place this could
be happening seems to be in the ntl network.

How common is transparent dns proxying amongst UK ISP?

I originally setup djbdns dnscache because it was easier than fixing the
problems with my NAT router's dns. I've hoped that it might give me
some protection against poisoning of the ISP's cache too, but I've never
really been sure whether I'm going direct to the authoritative servers or
not. I always get "round number" TTL values on the first-lookup, so I
would hope I am.
