“The East Kingdom Server will undergo a planned upgrade in the early morning of 3/21/16.
This is the first in a series of planned updates this year.
We will be migrating from Xen to KVM, which will appear to be seamless to the End User, but has the ability to use our resources in a more streamlined manner and offer a better user experience.
Time Frame 1am-2:30am Eastern Time
This is expected to run for 49 minutes.
During this time frame all East Kingdom services will be unavailable to the populace.
Tools that backbone or pull from the server will also be affected (IE: Email, Help Desk, List Server, etc).”
