For the community managers/moderators:
Please don’t delete, I know this is the question not quite about the code or technology, but I have no other places to ask it since the Reddit has banned me for political reasons, and there is no other poular tech-related places with large audience.
The question:
Recently I found neither VS nor browser can download VS extensions.
VS Installer shows loading icons eternally, and I can’t update VS even if I uncheck those extensions – the Install button is still unavailable.

I can open the webpage of any extension, but it never lets me donwload the VSIX file: download fails each time.

I checked it on two different networks – at home and at work. Other Microsoft websites and services are accessible and workign as usual, i.e. I can install Visual Studio itself.
