I've just checked my router, your suggested domains are already blocked but still got the update.
Maybe it was may bad, because I visited the eShop, because I've thought I'm on the safe side with the blocked domains.
I've started eShop, got the notification that there is a new update with the options 'download' and 'cancel', pressed cancel, checked the download section and saw the update was already downloaded. I dunno..

Am I allowed to visit the eShop even with blocked domains?
