[Savannah-hackers-public] new upcoming ns1.gnu.org server

[Andrew Engelbrecht]

Hi Guix and Savannah admins,

We're planning to change the IP address of ns1.gnu.org some time next 
week, to fix an issue with the installation that would normally require 
extended downtime. Because the server is a slave for the guix.gnu.org 
and savannah.gnu.org zones, and because our other name servers are 
merely slaves to ns1.gnu.org, we are doing this in a multi-step process.

If you could please add the IP address of `ns1-new.gnu.org` to the list 
of servers that receive transfers from your zones, that would be great. 
The new IP address is:

192.99.37.66

Note that this server isn't yet in our zone file or in our glue records 
as ns1.gnu.org yet, so it's currently inactive. Therefore if you could 
please keep the rules for the current ns1.gnu.org server, that would 
allow us to keep serving your zones prior to the changeover.

You may need to add our IP address to your firewalls, and to use the 
`also-notify` directive, if you're using `bind`, as our staging name 
server is not in our zone file as a name server for gnu.org.

There's no major rush, so if you don't get to this immediately, or if 
you can't get it working, that's fine. Let us know if you run into 
trouble. To debug the change, you could try running:

dig guix.gnu.org @ns1-new.gnu.org
dig sv.gnu.org @ns1-new.gnu.org

Anyhow, if you have any questions, please let us know. Thanks in advance 
for your help! : )

Andrew
