 ## Rate Limiting
 
-We only allow a certain number of requests per minute. We reserve the right to adjust the rate limit in order to provide a high quality of service.
-
-Current limit is set to 1 request per second.
+We only allow one request per second per source IP.
 
-In addition the service only allow 1 TCP-connection per. (IPv4)/24.
+If rate is higher that acceptable, we return: `503 Service Temporarily Unavailable`
 
-Meaning that `192.0.2.41` and `192.0.2.52` can not have simultaneous connections, but `192.0.2.41` and `192.0.3.52` can.
