A wild guess for me is that there is some kind of routing problem with Canadian ISPs. Given that it starts out fine then goes to 10000ms for me instantly that seems like packets are being routed through some weird route or there's some kind of bottleneck happening. Regardless, seeing as it is randomly affecting some people and not others I think it's safe to say that it's not a Warmane issue but an ISP issue.
There was this software I was going to try using called WTFast that apparently acts like RIP on a router and traces the best routing path to the server. Will report back if it works.
