The request limiting can be configured in multiple ways.  It is 
typically configured using $binary_remote_addr variable as a key 
(see http://nginx.org/r/limit_req_zone), and hence the limit is 
per IP address.  The particular configuration uses

: limit_req_zone "all" zone=all:100m rate=2000r/s;

That is, the limit is applied for the "all" key - a static string 
without any variables.  This means that all requests (where 
limit_req with the zone in question applies) will share the same 
limit.
