It seems Funcom has merged servers in AoC. I can only see this as a good thing, although I am sure some folks who have had to change their names will disagree.
This is still a great game with plenty to offer, and it really does need an environment that allows more people to run around together.
From what I can tell Ironspine was merged in with Set for PVE. Also for PVE Wiccanna was merged with Gwahlur.
Tyranny remains the de facto PvP server. While Cimmeria, Bloodspire, and Agony have been merged.
In regards to naming, apparently if several characters of the same name are all from active accounts, the one with the higher level will keep his name. If merged characters have the same level, the one from an account which is registered on a longer time base will keep the name (so 3 month recurring over 1 month recurring).
Guild cities were moved to the same playfield and spot they had been before. When necessary a new instance has been created. So every merged guild will have access to the same guild city on the new server.

There you will also find information about the free character transfer, and other items involving the merged servers that I haven’t touched on.
