Why we celebrate 404 Day?
404 Day is a holiday associated with the World Wide Web. Some say it’s unofficial Webmaster’s Day, some say it’s International Internet Day. In the U.S., it is about raising awareness about proper filtering of information from the web. Either way, the event is directly related to the World Wide Web.
The history of the holiday is unknown, but its date was not chosen by chance: 4.04 is reminiscent of a 404 error. This is the standard HTTP response code for a “dead” link. This error is considered the most common on the Internet, so it is known to many of its active users.
What Do People Do?
Internet users remember this holiday, on the expanses of which they actively share funny pictures about this type of error or tell about the problems in which it occurred.
Nevertheless, it is no coincidence that several holidays are combined under the date at once: the webmaster works to create sites that are then posted on the Internet. Links to various resources can contain both useful information and content that sometimes needs to be censored. But don’t be overzealous about restricting information. It’s important to keep track of which links should be blocked and which should be left available. Sometimes sites with useful content are blocked while malicious ones remain open. This is a common problem with many school resources.
How to Celebrate 404 Day?
404 Day is not a day off; there are no special events on this holiday. This event should be celebrated in the evening at the computer. You can browse interesting sites, order a T-shirt with a 404 print. It is also worth reading about online professions or even take a course in one of them to master a sought-after specialty.
