www subdomain not working
Fragment of a discussion from Support/LiquidThreads
If you think that adding an HTTP redirect is too difficult then that is definitely a problem. I'm 100% certain that there are incoming links which include a www subdomain so if you want incoming viewers to think the site is still functional, I would recommend adding it.
Redirects are hard nowadays, yes. See for instance phabricator:T133548. Closed.
Well, several dozen of them certainly are. Much harder than one to be sure. I don't see how no response--not even a 404 page--is preferable but that's where that incoming traffic will go: nowhere http://isup.me/www.translatewiki.net
