From time-to-time, Salesforce undertakes a maintenance operation called an Instance Refresh. This is performed for various reason, but primarily to maintain good performance. As part of this your org may be moved to a new data center. More information on this, and steps that might be needed, can be found in this Salesforce Help Document.

There are currently no Instance Refreshes publicised.
