Publisher Ubisoft has announced that it will be transitioning the hosting of many of its online services "from a third-party data center to a new facility" on February 7. During the transition, which is meant to "improve the maintenance of our infrastructure and deliver better uptime and greatly improved services for our customers," some Ubisoft titles across a number of platforms will be completely or partially unplayable.

Ubisoft preemptively apologizes to its customers for the inconvenience in the official announcement on the Ubisoft Online website. While there's no mention as to how long the transition of services will last, the publisher has provided a list of the games, platforms, and services that will be partially or completely taken offline during that time.

The following six games will not be playable at all during the transition:

• Assassin's Creed - Mac

• Tom Clancy's H.A.W.X. 2 - PC

• Might & Magic: Heroes VI - PC

• Splinter Cell: Conviction - Mac

• The Settlers 7: Path to a Kingdom - PC

• The Settlers - Mac

There are some games that won't be impacted by the transition at all. They are:

• ANNO 2070 - PC

• Assassin's Creed Revelations - OnLive, PC, Xbox 360, PlayStation 3

• Driver: San Francisco - OnLive, PC, Xbox 360, PlayStation 3

• Just Dance 3 - Xbox 360

• The Settlers Online - PC (web-based)

Ubisoft's announcement also notes: "The Online features of all games that are not mentioned above will be impacted during the transition. Offline modes will not be impacted."

As expected, the PC version of Uplay--the publisher's proprietary online game service--will also be offline during the migration. It's also stated that all Ubisoft websites will be "impacted by the transition," save for the Official Forums and Solution Center sites.
