Multiserver, but still dns offline

[klasje]

Problem: If 1 server goes down, everything goes down.

Current set-up:

Server1
domain.com with 2 ns records:
ns1.domain.com pointing to server 1
ns2.domain.com pointing to server 2

Server 2
Just hosting some other sites, all domains using ns1 & ns2
Zone transfer between server 1 & 2.

Assumption:
If server 1 goes offline, the sites will keep on working on other servers, as ns2 points to a copy of the dns zones.

Reality:
If server 1 goes offline, ns2 cannot be found (or is not used?) and all websites go offline.


What is the proper way to solve this?
I assumed ns2 would serve as a dns backup, but it apparantly does not.

multiserver does not copy your site , only dns info is there
so when your data is on server 1 and its offline dns still point to that server but its offline so it works like expected
