What is Magnum?

Magnum is the nickname for 1 of our 3 'Server Release Candidate' channels. When a new version of server is ready for the main grid it needs to prove itself in a release candidate channel for one week first. This is what we used to call a pilot roll. Once a 'Server Release Candidate' has proven itself it will be rolled out to the entire main grid. Magnum will then be given a new 'Server Release Candidate'. We might have as many as three 'Server Release Candidate' channels on the main grid at the same time. The others are BlueSteel and LeTigre. These can and probably will change on a weekly basis.

Magnum Release Channel

This is the Magnum Release Channel. Information on this release candidate is below. For more information on beta projects, see: Beta Server Office Hours.


Magnum is unused at this time.


We will normally roll Release Candidates to the grid Wednesday mornings when we have them. If we don't have one we won't roll anything. The RC has to be stable on the main grid for 6 days. If so it will be rolled to the full grid next the next Tuesday morning. During the course of the 6 days RC cycle regions on the RC cycle may be restarted more frequently.

Test Plans

Additional Info

"You gotta tame the beast before you let it out of its cage."

Magnum can be on about 10% of the grid. These 4 regions will always have the latest up to date Magnum RC code. You are welcome to use them as needed. They are available to members of the group "Second Life Beta". Please join this group:

If they are closed that means there is no RC using that channel.

  1. Magnum Sandbox 1
  2. Magnum Sandbox 2
  3. Magnum Sandbox 3
  4. Magnum Sandbox 4
