I just (09:50 CEST) tried out Gyula's download link:
It worked seamlessly without any interruptions via a 100Mbit/s VDSL internet line by "Deutsche Telekom" and took approx. 7 minutes on an Android Smartphone.
Download of a 2.7GB RAR-file with a 29.7GB image:

It does not seem like a problem on the hfsignals side.
BTW: as far as I remember you should add ".img" to the file name, to be able to use the raspberry imaging tool.?
