Hi Radio Bloodstream,
From what we can see the reason that your server was down was due to you downgrading your monthly bandwidth plan yesterday which resulted in you having less AutoDJ storage than when you were on your previous monthly plan. So you basically dropped down from 10GB of storage to 6GB yet you still had over 6GB of files uploaded to the server and you had therefore exceeded your storage quota which prevents the AutoDJ from starting.
We can see that you have since upgraded this back to the same monthly plan that you were on previously and you have now have that extra storage space back in place and the server is operating fine again.
