GeoIP and maintaining high availability

[Tomasz Chmielewski]

Hi,

I'm about to set up bind with GeoIP patches.

What I'm not sure, is how do you guys handle high availability?

Suppose I have zones for Americas and Europe, and a destination server 
in Europe dies - how do you handle it so that new (i.e. web) requests 
hit American servers only?

Set TTL to low values (i.e. 10 minutes max) and reconfigure the zones if 
European servers are down? Something else?

I assume typical hosting, without access to sophisticated network 
settings, like BGP.
