I will try to explain more detailed:
A large network provider can have hundreds/thousands of peers. These peers
receive the same /32 prefix. A large network provider has housing facilities
many places in many countries. 
* Put your server in some or all of these housing facilities. 
* Give every server the same IP address. 
* Tell large network provider to use the closest path and make a route to
this IP address where you have your servers (use a routing protocol or
whatever)  
* The peers of large network provider will be routed to the closest DENIC
server in large network providers network.
* If a server is down, the next closest DENIC server will get the traffic.
* There is no single point of failure here. 
* You are using anycast. 
* You have a multiple failover solution.

I hope this was clear enough.
