I have a particular page that I want to refer users who have DNS problems:How do I diagnose not being able to reach a specific website as an end user?However, there is a catch-22 -- users who are having DNS problems may not be able to reach our sites and read that page!Thus, I need a reliable long-term mirror of this web page on another domain, either for free or as a paid service. Ideally, one that would periodically ping the source and keep it up to date with any changes as well.I found some community built mirroring services to make sites Digg-proof or Reddit-proof but these are ad-hoc and not guaranteed to work for the long term.Are there any webapps that offer reliable long term mirroring of individual web pages? Or any other webapp I can use to achieve this functionality?
Mirroring a particular web page?

The only semi-reliable thing I could think of was linking to the page in the Google cache:http://webcache.googleusercontent.com/search?q=cache%3Ahttp%3A%2F%2Fsuperuser.com%2Fquestions%2F231977%2Fhow-do-i-diagnose-not-being-able-to-reach-a-specific-website-as-an-end-userBut you can't control how frequently it's updated, etc.  Also, not the prettiest of URIs (although there's always the shortened link).  And the Google cached URI scheme has changed over the years.  Maybe using the stock google.com query with the cache operator would be more reliable.
