Same issue here i am in 39.45.xxx.xxx IP pool and mainly play Rainbow 6. Few days back i was getting good pings to SEAS and EU servers but now ping is still fine to EU it is screwed up to SEAS servers. I reported them this issue about a month ago and provided my IP pool and game server IPs and they agreed to fix the issue and my pings were great until like 2-3 days ago and just recently got a reply from them that issue has been fixed but its much worse for me now. Replied back to them with my IP pool so hopefully they get their crap sorted out.
