Would this also extend to intentional actions that may have had unintended consequences, such as provider A intentionally de-peering provider B, or the monopoly telco for $country cutting itself off from the rest of the global Internet for various reasons (technical, political, or otherwise)?

That said, I'd still have to stick with AS7007, the Baltimore tunnel fire, and 9/11 as the most prominent examples of widespread issues/outages and how those issues were addressed.

Honorable mention: $vendor BGP bugs, either due to $vendor ignoring the relevant RFCs, implementing them incorrectly, or an outage exposed a design flaw that the RFCs didn't catch. Too many of those to list here :)

Friends,

I'd like to start a thread about the most famous and widespread Internet
operational issues, outages or implementation incompatibilities you
have seen.

Which examples would make up your top three?

To get things started, I'd suggest the AS 7007 event is perhaps the
most notorious and likely to top many lists including mine. So if
that is one for you I'm asking for just two more.

I'm particularly interested in this as the first step in developing a
future NANOG session. I'd be particularly interested in any issues
that also identify key individuals that might still be around and
interested in participating in a retrospective. I already have someone
that is willing to talk about AS 7007, which shouldn't be hard to guess
who.

Thanks in advance for your suggestions,

John
