Minecraft Junkie

No not junkie. My minecraft is down. I checked my wifi and I have all bars. Before, I logged out because my skin was a plain steve. So I logged out and went to try to change it back to the one I had.
It says something is wrong with the server. Is this just me and Hippo or is it a server thing?

Minecraft main server goes down once in a while, no worries

Thanks
