Hi Bert,

Is there any update on this bug, interested to know if you have found 
the root cause of it...

Also I have just upgraded one of our internal servers from Debian Etch 
and pdns-recursor-3.1.7-2 to Debian Lenny and the same patched version 
of pdns-recursor-3.2 that we use on the live customer DNS and the 
response time graphing for bbc.co.uk has gone up by at least double.  Is 
this something you have seen before at all, I am investigating from this 
end as well but the upgrade definitely caused this, I can send you the 
graphing seperately if required.

Its worth pointing out that even though they have double its still a 
good response time just not as awesome as the initial versions...
