I'm not sure if they are still being worked on or if it's just an oversight?
There is no sign at /warp tradeshop to say they are down which is where i go to check before calling people to my shop.

 

The plugin is being working on right now, so it's disabled.

 

Thanks Dew. And thanks to those working on it. It's a great feature of Skyblock.

 

I'll move this to help archive since your question has been answered
