Is anybody using this zoneedit.com service, it seems to be free :

What's failover for? How do I use this service?

Failover monitoring service works when you have two or more web servers running the same (or similar) web site.
First, you need one or more IP addresses or CNAME's set up for your domains, then you add the failover monitor.
The failover monitor watches your web server(s) by hitting a URL you specify and looking for text in the first 500 bytes of the results.
When the system detects that one of them is having an error, it pulls the IP address out of the list.
If none of the IP's are responding and you have a failure IP/URL defined, then it points the site to the failure IP/URL.
If the system can't get to all of the IP's, then it assumes that the fault is its own connection - and it restores the primary site. This effectively and safely keeps your site online - even if one of your web servers is down.
Any time the state of your service changes, an email can be sent to the "notify" email address.
