This morning Google’s search results don’t work.

Let’s say you search Google for water. Then:

Each result has a warning under its link “This site may harm your computer”:

Google search results page for "water"

Clicking on the link doesn’t take your browser to the page as usual, but brings up an error message.

Error page when clicking on a search result link

Clicking on the “This site may harm your computer link” produces a help page with the title “Concerns About Web Search Results: Results labeled ‘This site may harm your computer'”:

Google help page about harmful search result pages

So now I search Google for “Concerns About Web Search Results: Results labeled ‘This site may harm your computer‘”. The first result is a Google support page at

But accessing that page leads to another error (no screen shot):

We’re sorry…

… but your query looks similar to automated requests from a computer virus or spyware application. To protect our users, we can’t process your request right now.

What a mess!


  • Should visiting any web page really “harm your computer”?
  • On what basis would Google think that a web page is going to “harm your computer”? Does it take into account or even know what kind of computer you are using?
  • If Google had reason to believe a web page were to “harm your computer”, should the page be really listed as a search result? (Less is more?)
  • If a search result page is not marked with the warning, would you blame Google if you then visited the search result page and your computer came out “harmed”?
  • Are these search result page getting too crowded altogether? craigslist has barely changed their listing format and they’re doing just fine.


Of course, this was a temporary glitch. According to google’s blog, “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. [PST]”. (So I ran into this just towards the end, around 7:20). The problem’s root cause is given as:

Unfortunately (and here’s the human error), the URL of ‘/’ was mistakenly checked in [to a list of bad URL’s] as a value to the file and ‘/’ expands to all URLs”.

And it wasn’t’s list as Google had originally posted. (The two organizations work together on this list). Well, mistakes happen …
