No, it's not just you. I've had this problem for months and have called Apple and they say it's my ISP's problem and have called ISP and they said they have no known Mac issues. I have no problem connecting to the internet, just get that dumb -1001 error whenever I launch Software Update. It's REALLY annoying.
software update says not connected to internet Software Update says not connected to internet Can't attach files through webmail YouSendIt says not connected to internet Used to work. Whats going on please.
