No, there wasn't a hack. Even if you thought you were online because the server warnings weren't there, you weren't truly online. It was likely a cached version of the site.
The site is down, they're transferring tons of data. It's going to take some time.
Your stuff is safe, stop believing dumb people in chat who don't know anymore than the next person. It's as if people haven't heard of trolls before.
Stop asking the same questions, you ever load up your phone with music or a USB with movies? Well think about how many people use this site, how much data there is and how long it would take to get that straightened out. Then they have to SYNC THE WALLETS, you ever sync a crypto wallet before? Shit takes forever to download transactions. So stop the FUD and go away.
