Visitor origin

Hi, I have just installed Piwik and started playing around. It seems that all my visitors are originating from North-America. I can see how the “Real Time” log updates as I visit a website integrated with my Piwik. I’m located in South-Africa, so obviously the visitor origin should indicate South-Africa?

I use Joomla 2.5 and joomla 3 websites and installed Piwik plugins with tracking codes.

Hope someone can help with this.
