[Savannah-hackers-public] DNS replication

[Sylvain Beucler]

Hi,

When 140.186.70.68 sends a notification to ns1.gnu.org about the
savannah.gnu.org zone, something weird happen, because ns1.gnu.org is
usually updated after ns2.gnu.org, while ns2 is the slave.

I test with:
dig savannah.gnu.org SOA @ns1.gnu.org
dig savannah.gnu.org SOA @ns2.gnu.org

So apparently ns1 relays the notification, but doesn't update
immediately. It also takes longer than the TTL (300) for it to
refresh.

Do you know how this works?
