Cloudflare talks about having datacenters in 300+ cities. Presumably they have at least a few servers per datacenter. They saved 130 servers worth of memory... not even the minimum number of servers they have (seriously though, they probably have a LOT of servers)... a few GBs of memory per server running the service. At that scale this is a nice-to-have.
