Its not perfect, but we basically had our webserver make the same stat requests to two independent Stat Servers, so both Stat Servers are actively calculating the stats.
Thus if we lose a Stat Server, the web server would just use the alternate Stat Server. Or if the webserver goes down, the Stat Servers should continue calculating the stats. And as long as an "alternate" webserver requests the same stats, it should continue where the original left off.
At some point I'll play around with alternatives solutions.
