Cache problem.

[Thomas Kinghorn [MTNNS -Rosebank]]

Hi List.
Firstly, thanks for all the previous advice which has been wonderful.

My problem this time is:

I am using the local root server as the first option in "root.hint"

We have had an international failure and as a result, none of our
clients can get dns resolution.

I thought this would have been eliminated by using the local root cache.

In the root.hints, its server 'F'

Below is an extract of the messqges file
