According to Google Play, the initial realease for the PoC Survival Google Play Multiplayer Server was June 7th 2016. While working on how many in-game years and days the PoC Survival Server existed for, I had to find out how many IRL days of the Server's existence passed by, and supposedly this is the PoC Survival Google Play Server's 666th IRL day of existence. Spooky, xD
666 >.>
Yep! xD
667
