I’m playing League of Legends on the RU region, but there’s no RU option in the Game Server Location list for the LoL item.
I captured my actual game traffic and the server IP is 162.249.72.2 (subnet 162.249.72.0/24, UDP port 7378). Riot appears to have migrated the RU region to European infrastructure.
Question: should I select Europe West, Europe Nordic & East, or create a custom item with the 162.249.72.0/24subnet? Which gives correct routing for this destination?
Also, RTT check doesn’t work for this IP — Riot blocks ICMP, and TCP probes get no response. Is there a way to measure RTT to nodes without it, or should I just pick the node manually?
As you might already know, Riot Games has very strict firewall policies. They currently block both ICMP and TCP probes.
On top of that, they use anycast networks, which makes ping checks even more difficult. Because of this, it’s really hard to figure out exactly which country the server is routing to just by looking at the IP.
Out of curiosity, what kind of ping are you getting directly inside the game client? Let me know!
In-game ping is stable at ~70 ms on EUW. Average is fine and the problem is jitter, not latency.
I captured the traffic: server is 162.249.72.2:7378 UDP. Over 600 packets I get 14 gaps of 85-110 ms in the stream, while the client still reports 70 ms average.
Actually, root cause is on my ISP side, namely jitter on their access gateway (min 2 ms, max 90-110 ms, stddev 10-12, zero packet loss)
Thanks for looking into that. Since you suspect the jitter is coming from your ISP’s access gateway, I highly recommend using our mudmtr tool to test against the server IP 162.249.72.2.
Running this should give you a clear view of the routing path and help confirm if it’s actually an ISP issue.
Let me know if you need help analyzing the results!
