I'm new so sorry if you don't do .zip files or have a file limit but I have a MEGA download for all the maps I want put onto the fastdl. They are all .bz2 aswell.
MEGA: https://mega.nz/#!YX5mnK5I!XaIstDXAODdKY8x5O-1mSdE_IMqCcqULafgdxwi7Hgk
Also, do you have info on how to get workshop maps on your server? People can't download the maps so it'll be a big help.
