Are you using any downloaders or browsers for downloading it?
Finally resorted to wget from a Linux host on a 10G link.
Which file are you looking at?
The one next to the bottom:
GPL: DNS-325 A2 (1383.44 MB)
The downloads cwap out at about 1.1G (Read error at byte 1149722785)
I've checked a dozen different ways and the problem seems to be the server (Jakarta)
The files need to be moved to some place where they can be gotten.
