Service providers don’t identity their customers publicly, but it’s obviously possible for any provider to host a politically unpopular potential target for foreign enemies. The Democrats would consider my mentioning names as hate speech.
The video below from Cisco's Charles Germany explains how router loops and flapping can commonly occur. Considerable care goes into various fail-safe methods to prevent these problems.
