It's definitely not one load balancer, but nor is it 70krps distributed across 2000 servers. I also think having only one per datacenter would be a bit risky -- I'd have at least 2. It's very frustrating that the article doesn't make clear how many load balancers they run.

WordPress.com currently has 12 load balancers per data center. They are HA and used for different subsets of traffic.

Okay, so we can now do the "math" :

70 000 / (4 * 12 * 12) = 121.52 request per CPU
