The new update on minecraft is not letting me get on my servers

Whenever I get on Minecraft the servers appear to be working, so I tried to get on one. The first one didn't work, neither did the second, or third, etc. I am confused and worried that I will be forced to only play single player from now on. Mostly I am wondering if it is the servers' problems or Mojang's, or even possibly Java's?! I hope this can be solved by either Minecraft or the servers. I am hopeful for quick answers so I can get onto my servers as soon as possible!
