[Savannah-hackers-public] DNS issues

[Sylvain Beucler]

Hi,

I'll recap the DNS errors we currently experience:


- ns1.gnu.org refuses requests for dl.sv.gnu.org:

  $ host dl.sv.gnu.org ns1.gnu.org
  Using domain server:
  Name: ns1.gnu.org
  Address: 199.232.41.12#53
  Aliases: 
  
  Host dl.sv.gnu.org.formation.cliss21.org not found: 5(REFUSED)


- audio-video neither:

  $ host audio-video.gnu.org ns1.gnu.org
  Using domain server:
  Name: ns1.gnu.org
  Address: 199.232.41.12#53
  Aliases: 
  
  Host audio-video.gnu.org.formation.cliss21.org not found: 5(REFUSED)


- ns4.gnu.org lags (last version is oct 16) and thus is interfering
  with our IP changes.


- ns1.gnu.org doesn't replicate changes from savannah-backup.gnu.org
  immediately - it looks like there's something like an hourly refresh
  or something, while the TTL is 300 and the notification is sent
  immediatley, so we'd like to understand how it works.


Cheers,
