It is not just the server that is down. All of the Minecraft Servers are down. There isn't an exact time when they will be back up but my guess is like in 30 minutes, maybe more.
That's why you obtain games or other things to do for when this happens. It's not the end of the world, server resets and downtime are necessary. This is completely natural.
Well the whole time the server was down, I was in a park falling down a hill and twisting my ankles. - All good.
