HI All,

We currently have two colocations, one in Sydney and one in the UK. The problem we have at the moment is we here in Sydney have our own registrar and dns and the UK has the same. All the clients point to a public DNS that have A RECORDS that point to their own services in each colocation. Now the problem I see, if our services here die, we need to point all the client machines to the UK DNS, and when we are talking about thousands of clients, one can image the problem it poses.

Is GEO-IP the way to go here? Ive read that GEO-IP will know which zone you are in, and divert traffic to the closest service, and if an IP for a particular service is unavailable, it will redirect that traffic to the other zone. Is this correct?

At the moment we have a domain called, xxxxx.com. All our UK servers have DNS records such as xxxx.uk.xxxxx.com and AUS servers have xxxxx.au.xxxxx.com. Will we need to change this to xxxxxxx.com and GEOIP will handle where the traffic requests go?

The solution you're looking for I would say is a Global provider that is able to support ANYCAST.

Anycast DNS solutions have been around for a while, where you're routed to the nearest service location.

Might be worth some investigation as most providers can provide it if asked.

Hi BBRazz, is there any global company you would recommend? I am looking into UltraDNS but they are very expensive, something like 10 grand a year.
