    DNS Server: Centralized Clustered vs Single Diversified

    Sorry for the somewhat confusing title. My DNS setup right now is the latter, "single diversified" meaning, I host both the web server and DNS server on the same box per group of clients. For example:

    Client Group A
    NS1 and NS2 is hosted on the same box with the web server A

    Client Group B
    NS3 and NS4 is hosted on the same box with the web server B

    and so on...

    I am thinking of making a "centralized clustered" DNS server so that my setup would become like this:

    NS1, NS2, NS3, etc. would be on geo-separated servers all containing the same DNS info and they will host the groups of clients at Server A and Server B, etc.

    Now my question is, what are the disadvantages of the two setups? What I can think of right now is "centralized clustered" can be a single point of failure for DDoS attacks while "single diversified" isn't since only one group of clients will be affected in case of an attack. What you think?
