Someone might be hiding under that proxy - which is in Africa
He/she is probably using the "Proxy Server" setup common in most broswers...
ie: In Opera 10.5 latest beta go to settings -> advanced settings -> network -> Proxy Server.
In their you can type in some ip and its port number(must be and actual one) - and you will connect to the internet through there.
Its useful if you're doing some illegal stuff(lol), but it really hurts browsing speed - it REALLY hurts it ! http://www.whatsmyip.org/iplocation/ <-- Look up your IP's their/stuff's :D
