GGG always have launch problems in the first 2-3 hours of a POE 1 expansion. The last expansion 3.26 had around 500k players on the first day.

They've announced that over 1 million people have registered game keys, so that's double the last expansion launch. I'm hoping that the launch will smooth out after the first 2 hours.

I had queued to log in an hour before launch and the login server already crashed, so yeah.
