Hi, thank's for this detailed report and the discussion. I'm somewhat responsible for the mirror network, and I have heard reports about those bad network conditions from several places for some time now. I've tried to find more mirrors, but it's usually hard to get in contact with the right persons or even find a suitable institution. For example, to day I've added a second mirror for south america, which is probably an equally important continent. Does anyone have contacts to some suitable institutions in, let's say, Argentina, Uruguay, Ecuador, Ghana, ... ? Also, I try to make downloads work better by essentially to techniques: * torrent/metalink files. they basically tell a download-helper or web-browser to check for all sources in parallel and they also allow to resume partially downloaded files and checking them when they have finished. E.g. "transmission" is pre-installed on ubuntu and should be the #1 option for downloading sage tarballs or disk images. * compressing with lzma for those linux distributions where lzma/7z is installed by default. In the beginning, I got some reports that it is confusing, but for one reason or another this stopped. Probably, because "right-click > extract" just works. Also, it would be possible - on more modern distributions - to squeeze out even more bytes by using lrztar + lzma/zpaq. Has anyone objections or some experience with that?
