Looking for SMP

Hello! I am looking to once again play minecraft on an smp. Looking for something with at least a somewhat active playerbase and mostly vanilla without an insane amount of plugins that change progression.

Ideally looking to be on a reset world with the new world gen with the caves and cliffs update :)

​

Also I've been burned by servers dieing a few times now, and I know nobody can predict that but if there is something with an already existing playerbase I would prefer that. Maybe I am expecting too much but hopefully something great is out there...
