Earlier today, developer Shoghi Cervantes tweeted this picture of updated server stats in the worlds menu.
Now it will tell you if the server’s online or not. Servers can also put coloured text and player counters in the title for more info!
Shoghi is the developer of the server software PocketMine, and now works at Mojang working on Pocket Edition multiplayer. This is just one of his many future multiplayer improvements.
