Server merge

This event occurs only when a population of a server permanently dips so low as to make the server almost unplayable due to lack of total unique people playing on it. Essentially all characters from the merging server get copied over to a specific different server in hopes of bringing the player population back up to a healthier amount. This occurs very rarely and only under the most serious of circumstances.

In fact, this once happened to North American Servers of DDO, in 2007 July. Also, upon closure of European servers operated by Codemasters, European players were offered free character transfer to any existing North American servers.
