Bind 9.1.0 cache problem?

[Owen McShane]

Hi all,

we have several caching name servers which have recently been upgraded to Bind 
9.1.0

We now appear to have a problem with resolving anything held by 
fasthosts.co.uk:

$ dig fasthosts.co.uk ns 

; <<>> DiG 9.1.0 <<>> fasthosts.co.uk ns
;; global options:  printcmd
;; Got answer:

This was brought to our attention by someone being unable to resolve anything 
on the sil.org.uk domain, which exhibits the same symptoms.

Apparently both domains resolve fine with Bind 8.x

Anybody else replicate this, or have an idea what is happening?

Cheers,

Owen
