Rolling restart Wed/Thu April 16/17 for 1.21 Server Deploy

Wednesday, April 16th, 2008

[Update 2008-04-16 21:10] Several of the regions that received version 1.21 are showing problems, so we are going to revert them to 1.20. Many of the regions remain down; they will be back up within 1/2 hour.

[Update 2008-04-16 20:30] The deploy to 490 regions will begin momentarily

[Update 2008-04-16 17:00] We are in the middle of updating the central servers. Note that if you watch the concurrency plots, you will see dips in it as we restart servers that report concurrency numbers. This doesn’t actually mean that people are getting kicked offline, it’s just a reset of the data collection. The deploy to 500 regions will begin later tonight.

We will be doing a rolling restart this Wednesday and Thursday to roll out the patches to the server that were to be rolled out with last week’s cancelled rolling restart. Changes include security patches, performance improvements for Havok4 (including the issue that “openspace” or “void” sims have with Havok4), and code designed to mitigate the load on the central database systems.

We will do this with a usual 3-stage deploy:

  • Wednesday, April 16, 8:00PM : ~500 regions will receive the 1.21 server deploy.
  • Thursday, April 17, 5:30AM : ~1600 regions will receive the 1.21 server deploy.
  • Thursday, April 17, 6:00PM : All of Second Life will receive the 1.21 server deploy; this will take 5-6 hours to complete.

There will be no viewer updates required as a result of this deploy. All regions will receive warnings beginning five minutes before they are shut down. During the rolling restart, regions should be back 5-10 minutes after they are stopped. If your region stays down more than 20 minutes, please contact support.
