tl;dr for comments:<p>Article seems to fail to notice that gzip timestamps are specced to be timezone-independent, and two of the three example domains at the end of the article adhere to that spec. We don&#x27;t know what happens to the article&#x27;s &quot;10%&quot; number after servers that adhere to the spec are removed from the data. For all we know bing.com could be the only service that leaks this info.
