Google's first April Fools' Day hoax, the MentalPlex hoax, invited users to project a mental image of what they wanted to find whilst staring at an animated gif.
Several humorous error messages were then displayed on the search results page, all listed below:
  1. Error 001: Weak or no signal detected. Upgrade transmitter and retry.
  2. Error 666: Multiple transmitters detected. Silence voices in your head and try again.

Blogger "Google Weblogs (beta)"

The Blogger dashboard featured an announcement for Google Weblogs, or "GWeblogs," or "Gblogs," the next revolution in personal publishing. Features include algorithms putting your best content at the top of your blog (rather than publishing by reverse chronology), automatically populating your blog's sidebar with the most relevant content, posting directly into Google search results for maximum visibility, blog headers refreshed with images from Google's team of artists for anniversaries of a scientific achievement (similar to Google Doodle), and automatic content generation ('Unsure of what to post about? Just click "I'm Feeling Lucky" and we'll "take care" of the rest!')

Gmail Custom Time

Gmail's sign-in page and a banner at the top of each Gmail inbox announced a new feature, called Gmail Custom Time, that would allow its users to "pre-date" their messages and choose to have the message appear as "read" or "unread". The new feature uses the slogan "Be on time. Every time."

Around 11:00 p.m. EST March 31, 2008, on the newer and older version of Gmail, but not in the basic HTML version, in the upper right corner, next to Settings, a link appeared labeled, "New! Gmail Custom Time". The link led to a 404 error until April 1, when it led to the full Gmail Custom Time hoax page. Clicking any of the three links at the bottom of the page brought the user to a page stating that Gmail Custom time was, in fact, their April Fool's Day joke.

We apologize for the recent disruption(s) to our service(s).


Please stand by while order is being restored.


However the technology page describing the technical capabilities of the software remained at:

Technical Description

When using Google Books or GMail, a user would come across an announcement dated March 31, 2009 at 11:59:59, declaring a new "Cognitive Autoheuristic Distributed-Intelligence Entity". CADIE is also mentioned on the gBall FAQ page: "Google's new CADIE technology will interpret the data obtained from each ball to provide useful tips to owners". There was also a link on Google's Homepage for CADIE, and a blog entry in Google's official blog.

CADIE technology is also used to generate "senryu" (a type of Japanese poem similar to haiku) based on search terms for certain Japanese queries.

The Google Search homepage had a link to the CADIE announcement, stating that "For several years now a small research group has been working on some challenging problems in the areas of neural networking, natural language and autonomous problem-solving. Last fall this group achieved a significant breakthrough: a powerful new technique for solving reinforcement learning problems, resulting in the first functional global-scale neuro-evolutionary learning cluster."

YouTube

On April 1, 2009, YouTube gave some users a look at a new "viewing experience" when they selected a video within certain areas such as the "recommended for you" section. This new interface caused the whole layout including the video you were watching to flip upside down. Although the option was not visible for some, it could be viewed by adding &flip=1 to the end of a video URL. Adding &flip=1 to the end of a video URL no longer causes this effect, and the video loads normally. A page on "tips for viewing the new layout" suggested users hang their monitors upside down from the ceiling, although the layout did not reverse mouse-control.
