Here's a
minecraft server list.
I found a great minecraft server that I always play on but the thing is, it's very unpopulated, after the 2 days going offline, it used to have around 30 players max at some point but then after it going offline for 2 days it has around 10 max if you are really lucky, but it's a great server and admnis are very nice, oh and i am one of them, i became admin on the server not long ago so i can help you out if you decide to join :)
when you go in minecraft and click on multiplayer you then click on direct connect and type this in 178.116.54.126:25565
you can add it to your server list for faster login.
