It apparently has something to do with Google, when I use my de-googled LAN then I have described issue. Google is not my friend, any hope I could use Wiki without it?
It's a reasonable request for us to use fewer third party services, but the bug description wasn't particularly clear. Some effort to debug which services/requests are failing via e.g. your browser's developer tools would be appreciated if possible.
Some sort of DNS failure, currently mystery for me.
If you notice anything specific using Google, please let us know. I just did a quick check and we seem to be using assets.gentoo.org for stuffs.
