It's odd that I don't use SP for months, and then when it shuts down, I find loads of things I want to look up.

Frustrating though it is, I think they are doing the right thing by ensuring everything is functioning properly, before releasing. I think their problem is that they shouldn't have given a date when they would be back. Anything techy like this is fraught with unanticipated delays and unexpected issues always arise.
I am not following it too closely, and I don't have Facebook and the other thing, but I think in cases like this, they should give regular fairly detailed reports about the progress, so rather than vaguely stating "unexpected delays" they should give full details (in "tech speak") about the issue or issues, and what they are doing to fix them. Obviously if there are thousands of issues, they can't list them all, but perhaps just the larger more time consuming ones.
At least then people might get a better understanding of what is involved, problems that need to be fixed, and the progress being made.
