New update in their support website:

FileFactory is not closing down

The management of FileFactory.com have absolutely no plans to close down or limit the service. In fact we continue to grow, investing in more hardware and bandwidth. We have been online for over 7 years and we have no plans of going anywhere.

We have made great improvements to the quality of service over the past few weeks. As our server migration is now complete, the service is running much more smoothly.

Thanks to all our users and customers for your continued support!
IMO they should also let us know about when they'll resume making payouts as well.
