Before I retired I managed 26 servers for a university here in the US. It was always difficult to schedule down time for upgrades, system fixes, hardware installs, because the world is awake 24 hours a day. My servers provided a lot of important info to a lot of people all around the world. We had students, and faculty worldwide, not just on campus. Not once did I get complaints that someone was unable to access their data.
This is the proper time for these problems to happen, not after it's live in final release. Have patience, they'll work it out. Then we can all fly to our hearts content.
