'No new games can be created right now...'

I have 10,000 in queue to create or join a game.
From what I’ve looked up, this is a temp ban for creating/joining too many games per hour.
I was running baals with a full game, most of the players were joining at the same rate as me. Do they all get banned as well?
Are the server really this feeble that it can’t handle diablo2 games? I mean, it’s a 20 year old game.
Could there be another reason for this?
