This is where it gets complicated because they are not necesarily using one server in one datacenter to run the games, though they probably are tbh.
There is no means to tell when a particular conection will start to break down so even if you "ping tested" their servers, ultimately your connection could fail at any point.
A simple ping test or better, a traceroute will reveal if your network is stable. Ping /tracerouting to one of the server's IP's could reveal if they are currently experiencing problems, it isn't going to be 100% accurate since you could be put on a differernt server with a bottleneck in one of the nodes.
basically, unless you can prove it is lol with a accurate traceroute to on eof their servers when you're experiencing lag it could be your ISP and a pingtest.net should do you fine.
