According to everything on the Arch Linux Downloads page: https://www.archlinux.org/download/ archlinux-2016.07.01-dual.iso should be available.
The torrent tracker keeps saying "torrent not found". Via DHT and PEX, I have connected to more than 50 peers in the torrent swarm, and none of them had even a single piece of the file. All of the HTTP mirror links simply return 404.
Clearly the file exists, or there would not be a PGP signature for it. So could someone who has it please seed it at least once?
