We will proceed to a server update during this week-end.
The operations will take place during friday 22/02/2013 and saturday 23/02/2013 nights, and should not affect the accessibility of the grid more than one hour.
Hopefully, we will take this opportunity to update the simulators to OpenSim 0.7.5 release. Though we may keep 0.7.4 if we encounter non fast-forward issues with the new release.
