According to the article they have 2 thousand servers. These are Dual Xeon 5620 4 core CPUs with hyper-threading.
So that averages out to: 70000 / (4 * 2000) = 8.75 requests per second per CPU.
That seems like quite a low number, I would presume that the load would be shared amongst less servers than this and the others would be used for replication/redundancy.
