Are you using Spigot or something else?
Provide log files.
Provide config files.

got nothing to do with my server has everything to do with the server in the subject. :-)

:D
I just realised what a retard I am. I'm sorry.
Yeah it's down.

Try this one. It's a mirror: https://ci.lucko.me/job/Essentials/

Thanks, someone else mentioned the mirror but the build details are far off from the primary. The mirror shows build #8 when it should be 472 (latest). So its confusing if it is even valid.

Any idea when this will be fixed..? :(

It's back on.

confirmed - thanks!

The official CI server is back up thanks to @drtshock https://twitter.com/drtshock/status/865717250279526400
