Downloads stopping short

I host free web-only music releases on my site. We just posted a new release last night and now i seem to be having trouble with downloads from the server.

users are reporting downloads stopping short. these are RAR and ZIP files between 200mb & 1000mb and they seem to be stopping after a few dozen MB’s, leaving the archives incomplete

never had this issue in the past and am wondering what is going on!!


Are the files being served from direct links?
