So which employees of Mojang/Microsoft are going to be fired for this debacle?
Not only did you undoubtedly cause thousands of minecraft players to spend copious amounts of time trying to "fix" the lovely new textures but apparently your download servers are overwhelmed causing 3 megs of texture downloads to take hours.
This is not humorous. In fact, I'd imagine that you've left much of your playerbase that decided to play Minecraft on Easter Sunday rather angry and hostile toward you.
The managers/leads who approved this mess should be let go immediately.
