Once again, large swaths of the Internet in the United States were affected by a major morning network outage today [November 2]. This time, it was the Tier 1 network service provider Level 3 Communications that was at the center of the problem, which disrupted parts of the Internet's backbone. But for the moment, it does not appear that the outage was triggered by a denial of service attack or other network attack, like the attack on DNS provider Dyn on October 21.
[...] A Level 3 spokesperson confirmed that the company's networks had been restored to normal function by 1600 Greenwich Mean Time (noon US Eastern Time) but said that no other information was available yet.
The outage had no major impact on major streaming services that use Level 3, including Netflix and the HBO Go mobile application. But it did affect some customers' voice and Internet services. Level 3 suffered another brief outage a month ago, caused by a human error.

You forgot two layers, namely financial and political.
There, I fixed it for ya.
Jokes aside, these days at $WORK, I just send layer 8 and 9 issue directly to my $BOSS stating it's layer 8 and / or 9. He's cool and savvy and takes care of the b.s. for me. :-)
There is nothing that can't be solved with one more layer of indirection.
