I was able to log in from character selection soon as Enter World button lit up. After 3-5 minutes being in game, got disconnected and haven’t been able to log back in to the game since ( World Server is Down ).
However, some of my guildmates that were in queue when most of us got disconnected are still in the game now. My opinion is that the servers have hit the population cap. Despite their efforts to have layering in place to provide a smooth start, layering has no effect on server cap of servers. There is no other explanation of people getting that message when the game server is obviously not down.
Server population cap has been reached. You won’t be getting in until someone else logs out.
