I brought this up about 4 days ago. Here’s my thread: http://forums.dirtybomb.nexon.net/discussion/23762/south-america-server-really-u-s-east-server#latest
I’m sure they’re working on it. It appears to be a mistake in labeling in my opinion, or maybe something else.
TI thought I saw some actual SA servers (where my ping would be like 200+), but I don’t see them right now. The SA servers seem to have disappeared other than a couple. The servers give me the same ping I would have in a U.S. East server (where I live), so that’s why I thought it was a labeling mistake, but I’m not sure how servers work so it could be something else.
There’s been a lot of threads made on the forum discussing the issues with the SA servers in the past month. Hopefully it all gets resolved.
