With the @archlinux website being in the DDoSy state it's in this reminds me of something,

Please if you download the ISO with the Bittorrent link, seed it if you have data caps that allow you to do so.

Usually by this time of the month the link has been leeched to death which is sad because it's a useful resource
@BrodieOnLinux in my experience, a bunch of webseeds included in the .iso torrents seem to be doing the heaviest lifting. Here's my stat for August's .iso. Barely scraped 5 ratio with 150 Mbps upload speed available.
