RS also maintains servers sometimes, so some files also become temporarily unavailable for a short time.
Unlike MU, all temporarily unavailable files will be online at last.
However, very few files stored in RS can be only downloaded at 0 ~ 60 KB/s forever.
I think it's their hardware issue, but you can still finish this download job if you use IDM and wait some days (and that file will have 300 ~ 1000 DL counts in file manager).
Although the probability is absolutely low, I think I still need another site to backup my file.

Have any one tried peejeshare?
