After closing the servers, I received many emails with questions about the reason for the closure. And a few emails with questions about how you can help.
I've added the possibility of a donation to the site. It is planned to rent the Xeon E3-1246V3 16 GB server from loyal to p2p hoster. It can handle more than 250 000 active users. Rent is $ 99 per month. If we could raise half the cost the remaining amount I would have paid for itself.
