Add Akamai to that list of ASNs and you cover everything. I did that experiment a couple of years ago and my Apple devices went unresponsive unless I disconnected them from the Internet entirely.

The rabbit hole goes as far as locking yourself out of many government services. If you’re a Canadian, it means not being able to travel without submitting to corporate privacy policies and ToS (ArriveCan apps/website).

Unresponsive? As in the user interface stopped working?

Yeah, there are a lot of synchronous network calls in many applications. I ran out mobile bandwidth recently and have spent the last week in AT&T's penalty box and it's amazing what broke. For example, Audible's app goes to complete hell in this state when you launch it; you can bypass the hang by clicking library but it would be content to mostly just sit there.

I found a fun issue with the Apple Music app- if you're connected to wifi but NOT connected to the internet, it takes 60 seconds for the app to respond when you try to play something or change tracks.

DNS issues are the worst. Everything in your stack reports having a "connection" but everything takes 60 seconds to not even load.
