I run R2 server, It's non-dedicated so not running all the time. Bonus is timescale being normal as it gets accelerated if using core processors and running dedicated server. I'm hosting so not any real crap can go there without observation.
To join R2 install official AvP 2 18.104.22.168 patch and of course you need map if it's other than default map - use desktop icon join system to join cause it's most simple I think once you just know where to add that line
+gsa 1 +gsa_ip xxx.xxx.xxx.xxx +gsa_port yyyyy
(x is IP number and y is port number)
to join my R2 server use this IP and this port
22.214.171.124 - 27888
I inform here when I run server by sending messages like "server up" and deleting them once server is down.
