Splitting of authoritative from recursive nameservers

2007-04-23 - News - Chris Thompson

A few weeks ago we told you

We currently plan to lock down the recursive nameservers at and, so that they do not respond to queries from outside the CUDN and also do not allow zone transfers, during the first week of the Easter term (23-27 April). We will update you on this closer to the time.

We now intend to make these changes, at least insofar as zone transfers are concerned, early on Thursday 26 April.

We would like to thank all those who made changes to nameservers in their jurisdiction to fetch DNS zones from / instead. Logging has shown that the number of hosts still fetching from / is now quite small. Some final reminders will be sent to those who still have not made the change.
