It seems server7 was abused by leechers (such users only put files available for download and don't upload any website here)
We have removed some most active abusers and now it seems situation got better
Once I will finish 'Backup' tool, I will write some script to automatically detect such file leecher accounts, as they take over 50% bandwidth. Any if some active leecher comes it can make a serious damage by taking all available server bandwidth..
Anyway you should know that we use 10mpbs connection lines and on peak times connection can be slowed than in midnight. You may upgrade your account and get a server with 100mbps connection lines
