What is the server character capacity?

I really don’t care about queue times, it happens hard to estimate the viral popularity of this launch. Along with streamers telling 200k watchers the server they are picking.

But I would love to know the character capacity per server. Also, some clarification on the wording. Is this saying there is a limit to how many people can play at one time, or is there a cap on the number of accounts with characters on the server? just don’t want to wait in the queue if this is the case
