I've been looking to see how things are going with the Drunder Server but there isn't much information.
I did find a Drunder Thread on the Official Daybreak Forums https://forums.daybreakgames.com/eq2/index.php?threads/drunder.563174/
I haven't gotten through all 10 pages yet but there's all sorts of discussion and speculation, plus a report from at least one person trapped in the likely hellish realm.
Quite the experiment.
Interestingly a thread on EQ2 Flames is by the same OP who is apparently on Drunder in the regular forums. Hmmmm http://www.eq2flames.com/general-gameplay/100163-drunder-new-eq2-prison-server.html
