Habour Village Reef Cam

I haven't been on the YouTube for Habour Village Reef Cam in a few months, but it is covered in algae/coral polyps and no longer rotating. Is this common for it to go through these phases? I haven't seen it like this before. Or is it just not being looked after anymore?

I like to have it on in the background when I am paying bills and doing other mundane tasks on my laptop. I need my fix!
