Some pages are missing. I use gnome2-utils.eclass as an example, but there are more. Missing site: https://devmanual.gentoo.org/eclass-reference/gnome2-utils.eclass/index.html The google cache from Oct 19, 2019 09:59:36 GMT still has the content: https://webcache.googleusercontent.com/search?q=cache:bNTUZwP3YEIJ:https://devmanual.gentoo.org/eclass-reference/gnome2-utils.eclass/index.html+&cd=1&hl=en&ct=clnk&gl=us
There was a problem and now the issue is a CDN caching thing that should eventually expire. *** This bug has been marked as a duplicate of bug 698102 ***
