Yeap it seems like it might be on the host`s end. I`m seeing what IPB has to say but they may tell us to check what`s going on with our host (MyREINSpace is not on our own server). Unfortunately, that may have to wait until Monday, but I`ll call around and see what I can do!
I think it`s pretty unlikely that anyone would launch a DoS attack on this site, but you never know - pretty much all the downloads are targeted at REIN members, though, so most of the files wouldn`t be readily accessible to non-REIN members/bots who might try to pull that sort of thing.
