I remember the Unity Rally back in... September of 2012 where the Virtue server had 33 instances open for Atlas Park and I was wondering if anyone could remember how many players it took to fill up a zone to produce a second instance of that zone.
Thank you in advance.
100 people per instance, at least for Atlas Park. I'm not sure if it varied for other zones.
This article about the closing mentions it.
