hm. just checked it from my n900: everything seems to work ok. note that repo uses port 81 as opposed to standard 80, so check if your network allows connections to this port.

and i must say that my ISP is not the best one, so my server can be inaccessible sometimes (or so slow that it triggers connection timeout). just wait for a hour or two and try again.

if you will not able to connect for day or two (i'm assuming you're doing everything right and the sole problem is internet connection %-), drop a message here and i will upload .deb packages to some filesharing site. but this way you will not get updates and bugfixes. %-(
