On Thursday, January 10, the regularly scheduled downtime will be extended to 5 hours and 15 minutes starting at 07:00 to 12:15 UTC.

CCP will be taking the historic steps to merge two completely different games onto one server as we fully migrate Dust 514 to Tranquility in preparation for the upcoming Open Beta. While this unprecedented merger is an extremely exciting time for everyone here, it is also one that will require a great amount of care in order to ensure it goes smoothly.

Part of this downtime will be used for the actual migration itself; however, in order to ensure server stability and proper communication between Tranquility and the PlayStation Network, we will utilize several hours to test the connection and make sure the transition is smooth on both platforms.

We understand the length of this downtime is unusual but we feel it is necessary in order to minimize disruption to EVE Online and Dust 514. We apologize to everyone whose play time will be restricted or inconvenienced by this downtime and we will strive to have things completed as quickly and smoothly as possible. It is recommended that everyone place a long skill in their training queue in order to prevent any disruption of your regular skill training. Please note that while we anticipate that this will be the full amount of time required for migration and testing, we may need to extend by another hour or two should it be necessary.
