> So I added a second A record in CloudFlare for the blog to my home address, and again utilized the CloudFlare Proxy Services.

Is cloudflare detecting downtime via their proxy or something? I don't understand how you can pull the plug and have your VPS route not eventually fall over once cf's cache invalidates. Do browsers try both if one server fails?

Honestly I'm not 100% sure. Full A record failover is a paid feature which I don't pay for, but it seems like adding 2 A records does more than just round robin the DNS

If from a test machine I am loading the site via the VPS and I power it down, as soon as I refresh the page it ends up pointing home with zero downtime

I guess the proxy IP is the same. They must just run a single tunnel per hostname with multiple upstreams.

Nice find ;)
