I have been to three different servers trying to find a home. Each server says "24/7"...... They lasted a few days... Now I'm back to no server... Each time I must start over again... I'm sick of the same quests and I'm sick of losing progress. I would like a server to call a home. I do not play single player and I don't plan to.
You can try [kG] kunix.org -PVE-. I've been online for almost a year now.
The only time the server might be down is if it crashes (see posts about linux servers) or if my ISP has maintenance.
I can vouch for this server :)
Been online for a looong time!
And also we have recently changed the way a few things are handles, so crashes should be almost non existent now.
