Yes there are problems being faced right now
But be fair to the devs in these times - They're working on fixes, and opening extra blocks/ships as we speak.
I doubt they expected such a huge wave of players, since the release was supposed to be NA only, but as we know, many people have changed their regions to access the game regardless.
Log-in issues are due to server maintenance at the moment, and opening new ships by the looks of things.
-- In-game lag at the gate, and other populated areas is (suspected) to be due to GameGuard limiting information, which is extremely obvious to see when there are lots of people logged in, and thus lots of information being limited.
Hopefully the devs can find a solution for this in some way ASAP, and I agree that it is frustrating (Especially with a lack of communication right now); but show them support, not hate.
EDIT 01: Reading a lot of these replies, I do understand your frustrations about the situation, I share those frustrations too!
I'd love there to be more information and transparency about what is going on right now.
However, being mad online isn't going to solve any of that.
ALSO in regards to lag issues, from what I've seen and heard, those issues are partially to do with overpopulation, but it's because of how GameGuard works.
APPARENTLY GameGuard limits the information being processed, which causes some stutters for people, and this is increasingly obvious to see when there are more players, and thus, more information that has to be processed; but that is a completely separate topic again.
In the regards to lag and performance issues, we'll have to hold out for a more solid fix or patch to sort that out - I've seen some loophole methods that have fixed issues for some people, but the methods are a bit sketchy in regards to the game's terms of service
