New World just came out, probably a bunch of people waiting in that over 9000 login queue.
Heard their servers have a capacity of 2000 players and have a total of 233 servers globally. They said about 700,000 people trying to log in that 466,000 spots.
For those that dislike the ship system, server capacity has always been an issue for MMOs. Earlier this year, the mass influx of players on FFXIV overloaded certain data centers and SE/Yoshida apologized for unable to meet the demand. Most MMOs I played all have separate servers to not run into issues. I heard people bring up BDO, I haven't played it but from what I heard, it is 1 server per region - you are allowed to switch channels but not actual servers (like transfer from NA to EU).
