After a long bit of extended maintenance last night for patch 3.3, and after fighting with add-ons and general instability, many players were greeted with a familiar and disappointing message from sever.
Heads exploded, babies cried, and anarchy ensued as people once again saw this dreaded error. We've been told for months that the cross-server instances and other solutions were supposed to fix this, that they would be the salvation to all our problems.Additional instances cannot be launched, please try again later.
Not so. At least, not yet.
We are told by our sources that the central problem likely lies in there being too many players attempting to run instances. Before, if you had a server-wide instance capacity of say 1,000 instances open at any one time, you now have a battlegroup-wide instance capacity of over 10,000 instances open at any one time (just making these numbers up for the sake of argument here).
Last night, in the rush to try out the new dungeon finder and cross-server mechanics, the battlegroup-wide instance capacity was reached and destroyed in a blink of an eye. You had literally tens of thousands of people running instances in each battlegroup, entirely overwhelming the system.
