Update 4: Work is proceeding on Plan B to provide additional long-term resiliency.
On a personal note, I would like to thank the community in general as well as some select fellow site administrators (who may not want to be named?) for the support over the last week. This is of course the internet, but overall, the feedback and communication has been far more positive and constructive than I would have ever expected. While some core issues remain, there are no plans to shut anything down at this point, but it should be emphasized that this website - and most websites like it - ultimately have a truck factor of 1. Changing that would be very difficult for several reasons, which means that there should always be usable and independent copies of any valuable data available.
