Can't connect to Minecraft sever?

Alright so.
I was playing Crazy Craft on minecraft while skyping my friend. Next thing I knew, I was getting time out, blah, blah, blah. I could still skype my friend fine. I had to go, and when I came back, I had to restart the modem to get the internet back. Whennever I refresh the page now, it just says 'Can't reach server'. Just before, it showed the banner, but when I clicked on it, it just showed 'connecting to server…' It is a reasinably close server, too (400ms).
