The fastest way to download is via torrent, I’m currently seeding all images available and am pushing approx 300Mbps (megabits per second) across my servers and have done 200GB+ of bandwidth in under 3 hours.
I will be updating most of my servers over the next few weeks/months and will start updating my tutorials again, happy testing.
