Super Happy Hours for Premium users
July 3, 2009
To test parts of our new infrastructure, we have just disabled any traffic limits for premium users. This means unlimited downloading for all our premium customers. Have fun! Please notice that we may revoke this feature at any time without prior notice.
I guess they changed a bit at their servers, maybe that's the reason for your problems. If your ISP is blocking RS-service, then i think you wouldn't have any access to the site.
If you upload via browser, try to change the carrier (telia, global etc) and make a test with some smaller files.
This new infrastructure may also be the reason that i can't download with full speed now (only about half the nominal speed), but i guess i'm not the only one who is downloading now (and saving traffic)
