More dns and failover

[Lyndon David <lyndond () sentinet co uk>]

Hi all,

I recently posted a message regarding failover of geographically
dispursed systems
and had several replies. It appears that I discribed Ciscos distributed
director.

Thanks for the replies.

Does anyone know of any competing products to this or are they alone in
this
field?

I would also like to talk to anyone who has used this in DNS rather than
HTTP
mode as the system I am designing uses more than just HTTP.

Thanks, Lyndon
