Try clicking on a link that will take you there. Cause sometimes when you click enter you even click a link you may be accessing it at the exact same time as someone else, and your packets are getting lost in the void of the Internet. Try waiting a few seconds, usually helps me out when links or sites aren't working.
or if you really believe they are down trying doing a tracert to google.com
start > run > cmd
type tracert google.com
