When I last troubleshoot on this about 4~5 days back, certain maps were giving me ping of 1k~2k while some were nominal of around 280~350.
After some digging with tracert, I found that the map that had terrible ping, route the traffic to Telia Company in EU rather than through NA.
Tracert result to 35.169.158.36 with 1.3k ping.
