Is the internet broken?
Apparently, Google was having trouble this morning. Every search result from a Google search (even google.com) is tagged as "This site may harm your computer" and links to the Google page to that effect. From what I can tell, every single site on the internet is being blocked from Google search results.
A little while later, the message became "Forbidden" - I'm guessing this is a result of Google employees working feverishly to correct this problem. So far, I haven't found any news stories about this, but I'm sure it'll be explained before long.
In the meantime, I've been teaching people how to type "yahoo.com" into the address bar instead of the Google search box - I told you this chart was accurate.
