Good point, especially if you are hosting the server yourself.

Many thanks to all who offered suggestions - just to clarify It was a
DNS service that I wanted. Next time I post on a subject like this I
will try to be clearer as to my needs. In my own defence it was a
somewhat stressful time!

For the benefit of the archives - while it may not be my long term
solution - what I have done for now is to establish a secondary DNS
server with FreeDNS (http://freedns.afraid.org) and modified my name
server entries to include references to their name servers.

In other words my name server list now looks something like this:

ns1.mydomain.com
ns1.afraid.org
ns2.mydomain.com
ns2.afraid.org
etc.

I've already seen the effect in action as the two mydomain servers at
the top of my list failed yesterday for a short time and my sites were
still reachable via the secondary servers.

I will never trust my DNS resolution to a single company ever again.
It seems that no matter how big you are and how much redundancy is
built into your network it is still next to impossible to handle all
conceivable DDOS attacks if the bastard initiating it os sufficiently
smart/determined.
