Re: NSI Bulletin 098-012 | New GTLD server

  • From: Simon Leinen
  • Date: Fri Sep 11 07:50:26 1998

Is GlobalCenter the intended location of the K.GTLD-SERVERS.NET?
What was wrong with the LINX service network where the
K.ROOT-SERVERS.NET is installed?

When K.ROOT-SERVERS.NET was moved to London, we invested some effort
to optimize routing towards the LINX from the European research
networks.  Is the plan that we do this again for the new gTLD server?

Right now a query/response to the new gTLD server in England takes
four transatlantic hops from Switzerland.  I don't really see the
improvement with respect to the other name servers, except for those
who peer with GlobalCenter in Europe.
