Thanks for the quick replies.
All computers on this network are having the same results. So, I thought it was my network. I checked firewall rules, anti-virus settings, etc. Even tried rebooting the computers, routers, and broadband modem. Pinging gnome.org and its ip (18.104.22.168) times out. Nobody else in the neighborhood - most are very elderly
- is on the internet. Friend in another town (same county) also having trouble. Is it possible it's just a temporary problem for my geographical region? I think I've done what I can on this end - pixellany verified the site is up and running. Perhaps a call to my ISP.
Again, thanks for the quick responses!
