We have the checker script checking certain endpoints on our services. Most of the endpoints use a real wiki page on a real wiki, for summary it's Barack_Obama for example. Sometimes these pages are vandalized which creates alerts in production while in reality the service works correctly. We need to switch all of the checks to some page with more protection, or create a special testing page in the User namespace, protect it and point all of the checks to it.
