I cannot believe ten years ago today was the day of such terror that hit New York and all Americans. Today, on September 11, 2001, is a day no one will forever forget. Everyone I know, remembers what they were doing, where they were and the events of the day.
To remember 9/11, this year, Google, Bing, Yahoo, Dogpile, Ask.com and other search engines have special logos, themes and messages to remember the day and the Americans lost that day.
Google has a small black ribbon with text that reads "Remembering September 11th" linking to a blog post.

Bing has a very nice home page theme:
Yahoo made their whole top bar black, never seen that before from Yahoo:
Ask.com:
Dogpile, they even change the O in their logo:

The search industry has typically done special logos or themes to remember the horrific day. Here is the 2010, 2009, 2006. I do not have the other years here.
Now, a lot of you ask why not a Google logo? Google does not do logos for sad occasions.
Finally, this is an image of the Google home page on 9/11 ten years ago, when many news sites couldn't handle the traffic of those all rushing to the internet to find out what was happening...

There is no message with link at www.google.com from Germany. Even with a usa-proxy it's normal as always. Tested with several browsers. But I will always remember and your article gave me the link.

Reluctant as I am to give credit to msft, the Bing page was by far the most striking. Definitely something that makes you want to pause for a moment and reflect. If I remember correctly, on 9/11 & the days after, Google even set up a directory for people that were missing to link with their relatives who were looking for them. I was only 15. It was all really surreal to me then, but its pretty real to me now. Took a while.

Well that is nice, its a good move by all search engines. Big Nations won't forget their past. May God bless us all.

Not that I consider it a duty or a necessity, but I noticed that not a single web search engine thought it worth the trouble to create some neat little graphic concerning the worst domestic terrorist attack on American soil. But they shouldn't feel bad - every flag I've seen today has been at full mast meaning that our own government has forgotten the misdeeds of Timothy McVeigh. But that's ok, I will never forget the one hundred and sixty-eight empty chairs that adorn the lawn beside the reflecting pool, between the gates of time in the heart of Oklahoma City.
