[dns-wg] Planned maintenance for ns.ripe.net, 4 November 08

[Apologies for duplicate emails.]

Dear Colleagues,

This message concerns people who have ns.ripe.net listed as a
secondary DNS server for their reverse DNS zones.

In order to improve the quality of our service, we are adding additional
servers to our infrastructure. The effect of this change will be that we
will perform zone transfers from more then one IP address within
the ranges 193.0.0.0/22 and 2001:610:240::/48 as documented at:
http://www.ripe.net/rs/reverse/reverse_howto.html

On 4 November 2008 at 11:00 UTC, ns.ripe.net will move to a
load-balanced solution. No noticeable downtime is expected.

If you would like to make sure that we can properly transfer the zone
from your server after the change, we recommend that you follow the
following steps:
- Increase the serial number in your zone's Start of Authority (SOA) record.
- Wait for a zone transfer to be initiated from the 193.0.0.0/22 or the
IPv6 address range.
- Now you can compare the zone serials on your master server and
ns.ripe.net. To compare the serials you can use tools like "dig",
"drill" or "host -C" to query the SOA record and compare the serials on
both servers.

If you have any further questions about this message, please contact us
at dns-help at ripe.net
