The web page at example.com is maintained as a courtesy by IANA in order to explain the purpose of the example.com domain to wayward humans.
In the nomenclature of RFC 2119, one MUST NOT design computer systems that rely on the correct operation of an HTTP server at that domain. [0] Plus, it's _really_ rude to pound on a small-scale service being provided as a courtesy... go hit the home page of a tech megacorp (such as Microsoft or Google) or the status page for a major CDN (such as Cloudflare or Akamai) instead!
[0] I expect that someone here will want to pop up with a "gotcha" where they say something like "Oh, but IANA's email says that automated use is strongly recommended against, rather than prohibited and besides, they can't actually stop me from doing it!". To that, I reply "Sure, and standards-writers can't actually stop implementers that do the profoundly antisocial thing and do the things they MUST NOT. As any adult who's been paying attention to the world around them throughout their lives knows, there's only so much you can do to stop people who are very determined to be enormous assholes.".
