About Down Now Checker

This UserScript is a simple tool that allows users to check if a website
is down or not using the Tampermonkey extension. The script does the
following:

• 
  It registers a menu command called "Check if Site is Down" in the
  Tampermonkey menu, which can be accessed by clicking on the Tampermonkey
  icon in the browser toolbar.
  
• 
  When the user clicks on the menu command, it prompts the user to enter
  the hostname of the website to check, such as www.example.com.
  
• 
  If the user enters a valid hostname, it redirects the user to the
  website
  https://downforeveryoneorjustme.com/, which is a service that checks if a website is online or offline.
  
• 
  If the user does not enter any input, it alerts the user that no input
  was provided.
