Everything was reset

Did Aternos reset their servers? I logged back on about a week of being inactive and I see taht my whole entire world is gone as well as my plugins. Is there a way to recover the files?

I have another question. I have the essentials plugin and I want the disposal sign but I am unable to get it. I have a sign and typed in [Disposal] but the text did not turn blue and it does not work. It is a regular sign instead of a disposal sign.

I have a new problem. I was able to backup the server but after an hour, my server was deleted from the server again. What is happening?
