In South Africa you are more off-line than online, and the number of repertitive classical pieces are alittle off putting, some bing repeated three times in the space of 1 hour.
As far as I can see from the status page, there haven't been any major availability problems lately. I don't see other complaints about it in the forums either. If you're the only one having problems, it's quite likely that the problem is your ISP, not last.fm.
