[RESOLVED 12:57pm PDT] We have completed the server rollback at this time. Regions are now back on the 1.38 server.
[UPDATED 11:15 am PDT] An important clarification: We’re rolling back to an earlier version of the server software. This is not a content rollback, and will not affect recently placed objects or recent modifications to your builds.
[UPDATED 10:55am PDT] We are in the process of rolling back regions that are on server 1.40 to 1.38 due to some technical issues that affected a small amount of our residents. Please monitor this blog for any new updates.
[Posted 11:05pm PDT, 15 Jun 2010] Server 1.40 will be piloting this week and deploying in full next week; apologies for the late notice. The big ticket item in this release is the new version of the Havok physics engine (version 7). This has been a very complex piece of software to plug into our system, and has spent much time baking in QA. Still, if you are part of the pilot and notice any physics bugs, please file a JIRA to let us know.
The schedule for the roll is going to be:
- 2010-06-16 7a: 20% sim pilot roll 
- 2010-06-23 7a: 100% remaining sim roll
More information on Server 1.40 can be found in the Beta Release Notes.
Regions should be down no more than 30 minutes; if your region doesn’t come back up in that time, leave the region name in the forums and we will investigate.
