If you tried to use Google's search engine today and found that every result on every page displayed the message "This site may harm your computer" then you we4ren't the only one. I got it and thought either I had a nasty virus or Google had been hacked or had done something silly. It turns out it was the latter, Google messed up.
"12:38 p.m. ET: Google has posted an update to its official Google blog that attributes this fairly major "oops" to human error: "We periodically receive updates to that list and received one such update to release on the site this morning. Unfortunately (and here's the human error), the URL of '/' was mistakenly checked in as a value to the file and '/' expands to all URLs. Fortunately, our on-call site reliability team found the problem quickly and reverted the file. Since we push these updates in a staggered and rolling fashion, the errors began appearing between 6:27 a.m. and 6:40 a.m. and began disappearing between 7:10 and 7:25 a.m., so the duration of the problem for any particular user was approximately 40 minutes.""
So there we have it , Google is human after all!
