[load balancing] 2 Colo's

Hi all,

I'd like to hear your input on the best way to bring a second collocation facility online. We are a SAAS company. Basically, our service is all tied to a domain name; the www record.

It was my intent to use 2 A records to the WWW lookup. Then, use GSLB to control the traffic.

This works fine when both sites are up and running, but what happens when one goes down - rely on the built-in failover mechanism is DNS (the second A record)?

There's a GSLB Page of Shame http://www.tenereillo.com/GSLBPageOfShame.htm

Would love to hear your input as I am going to be bringing a second one online.

Thanks for your time,

dane
