Skyblock server down?

i stopped playing minecraft for a while but i wanted to get back to my island, which i spent tons of time and work on my island, only to find out that it won't let me connect. is the server down for maintenance? or are they taking skyblock off the server?

 

Skyblock is down. We're not removing it from the server.

 

I think the files were corrupted or something, there was some glitch so they stopped the server
