Ale komentuje, napriklad v RFC 1912 (Common DNS Errors) se doctete:

[zacatek kapitoly 2.8]

   You are required to have at least two nameservers for every domain,
   though more is preferred.  Have secondaries outside your network.

[konec teze]

   It's important when picking geographic locations for secondary
   nameservers to minimize latency as well as increase reliability.
   Keep in mind network topologies.  For example if your site is on the
   other end of a slow local or international link, consider a secondary
   on the other side of the link to decrease average latency.  Contact
   your Internet service provider or parent domain contact for more
   information about secondaries which may be available to you.

				Have a nice fortnight
