I know that you aren't on the same continent, however FSC have 'few' servers in USA as well.
I am sure that none of speed issues have anything to do with you. It must be some of the carriers that caused this. (Softlayer network) As you can see, some users have 8MB limited speed, per file, like me, and some drastically lower.
Exactly same thing is happening with FSC. However, upload speed to their USA servers are fine, while outgoing traffic to EU is crap.
I have dedicated server, with SAS drives, and I am affected too, no question is it my server, because I saw the exact moment when speeds dropped to both file-hosts.
Problem is somewhere in between, with middleman. The one who is delivering my traffic to your servers.
And tracert doesn't tell anything, where's the problem.
