I've run a couple of test before posting, so yeah, no need to tell me to port forward, power cycle, et cetera. But it is only now where I realized and tried connecting to PC EU from SEA. My connection went through, with the usual 210-350+ ping same as when I'm playing in NA (a few milliseconds delay, I know I've been playing like this for almost 4 years, and I'm used to it.)
So I decided to do a simple tracert and found out that my connection to NA would time out every time it reaches Akamai's beloved servers. And yes I'm familiar with Akamai, since I've encountered them in the past where I can't connect to Steam because my connection would time out upon reaching their servers, and I've also tried launching the game through both Steam and non-Steam launcher, or directly. The results are the same.
Compared to the EU tracert result which seems more stable though with pauses, was able to get through, as in through less third parties it seems. The NA result seems like it had a rough landing on Mars and did not manage to recover.
Also I've seen at least one other post from someone who's playing from SEA with the same concern. So I thought maybe you know, it might be beloved Akamai. So can you talk to them about that.
Rectitude carried to excess hardens into stiffness; benevolence indulged beyond measure sinks into weakness.
