I'm Hosting, 1 Jupiter (upgraded from saturn), ordered and paid July 16th. Still in PAID status, still waiting on hosting...

I wonder if they're just mining with our Hosting units.
I don't think so. I am in the same boat with hosted Saturn 39xx (ordered and paid 18th of July).
Here's a reply I got yesterday:
Hi,
We are aware that there is also a delay with the hosting compared with the shipping orders, but the engineers are working to get your miner up as soon as possible.
Thanks
Emilia
