There's a message on a cached version of the homepage saying:
POSSIBLE FUTURE DOWNTIME Dear Sinless users, the anti-piracy company BREIN has filed a complaint against our hosting company Leaseweb.com. Leaseweb is forcing us to move hosting companies and giving us 48 hours to move ... We are purchasing other offshore servers immediately, there might be a few days of downtime until we are back, please be patient!
