[outages] this list/host work in the coming week

I am working on upgrading the hardware of the host that hosts this list. I believe I have a comprehensive list of tasks that run on this host that I will be using to migrate the services, but wanted to warn people that the host will be undergoing work in the coming week. This is not only a hardware but an OS change as well, so a fairly large project to undertake. If you have questions, please direct them off-list. This should be a nice upgrade in performance across the board. - Jared
