This is Google using the power of their private network. A single IP routed to your closest data center which can be done because your traffic enters their network at the closest POP and they can then route internally. Currently, you have to do this using anycast DNS – Google is making this a really simple product to get completely automated geographic redundancy/local serving of content. Dyn charge a lot for this product.
Softlayer has a similar product called Global IP where traffic enters their extensive network at the local POP. You can then reroute the IP to any of your servers but it’s not load balanced and is really just another IP. Still a good product which we use to power all our services for automated failover. But Google just one-upped them.
Think AWS elastic IP, but Softlayer allow you to route to any server in any DC. And Google allow you to automatically route to a pool of servers in a location closest to the user.
