since the old fastdl down a while ago, i decided to make a new one on my spare webhosting,the server is hosting in US so speed should be good for US or EU servers
To using the fastdl hosting, add following lines into your server's configuration file:

sv_downloadurl "http://frisa.cf/cc/"
sv_allowupload 1
sv_allowdownload 1

if you want to know what map available or add these maps to your servers,pleace check:
