Other servers are much, much worse, population wise. Pleiades just merged with Rebirth, both mostly deserted. From Reddit:
“Pleiades never recovered from the server debacle they had a few months ago, when they had to shut down and relocate... before it was a small server, but active, more or less on par with Rebirth; after it was pretty much deserted, 1 or 2 people online, sometimes none.”
