I am having the same issue as OP. I am going to change my DNS settings and report back.
Also this happens on IE, Opera, and Chrome. Fresh installs, and in browser safe modes.
UPDATE:
The download page located
here redirects regardless of DNS.
Tested with Google DNS, OpenDNS, TWC DNS.
The landing page is
http://farmvillerelates.ru/blognaturallanguage.cgi?8 and seems to be missing from Google DNS, OpenDNS, TWC DNS.
This is not on the users end and seems to be coded into the download page somewhere.
Here is a DNS cache report supporting this. Notice how all locations point to the same IP.
So I agree with OP. Official site is indeed down.
Can someone share AOS 2.13? It's not on filetrip.net
