In order to address the "llSensor triggers on region crossing" issue identified after the Second Life 1.11.0 roll-out we will be initiating a rolling update of the servers at 7AM SLT/PDT on Friday, July 21th 2006. It should complete by 12:00 Noon SLT/PDT.
The effect on residents is that each region will be restarted once at some point within that 5-hour window. An automated warning will be given in advance within each region to give residents time to move to a new location.
