Impossible to connect to Skyblock1- not full

My brother and my friends tried, everyone on the server is saying they cannot get onto skyblock 1. All using different internet. I had to get in the oitc way due to me being on skyblock 1 and I could not log on with play.itsjerryandharry.com.

Lots of people at the lobby said they could not get in.
What is going on, I like Skyblock 1!
Please help. All the other Skyblock servers are ok, but not 1 :(

 

Skyblock1 has simply crashed, and it needs one of the owners to manually reboot it.

I have no idea how long it will be until one of them logs on, but it shouldn't be much more than a day.
