Ok. That data gives me an assumption that DNS works. That means that your network connection gets an IP address from the domain. One thing that seems to differ from the nokia repositories is that it uses https and maemo repositories use http. The difference there is that HTTPS-protocol uses a different TCP-port. How are you connected? WiFi or 3G? Could you try and go to this address with your browser on your n900: https://msp.f-secure.com/web-test/ The idea is to test whether you can go to a https-protocol website. When you go to the website, the browser should also popup a yellow text giving information about certificate authorization or something like that (in your own language). You should see a web page that informs you're on F-secure mobile anti-virus test page.
