One of the changes that went out in the 1.21 Server codebase enables us to alleviate database load caused by “spare” simulators – processes waiting to pick up regions after a restart. Unfortunately, a bug was found that prevents us from enabling the service. The bug did not hold up the 1.21 Server deploy significantly since it affected hosts in only one of our co-location facilities, and the new service was disabled within a few minutes of this being noticed for those hosts.
To send out a fix and reap the benefits of lower database load we need to do a follow-up rolling restart to 1.21.1 Server. (We’re as thrilled as you are.) There are no behavior changes. No new viewer is required. Each region will be given a 5 minute warning and then restarted.
