[cs615asa] DNS Flag Day

[Jan Schaumann]

Today is DNS Flag Day: https://dnsflagday.net/

We'll cover DNS in detail later in the semester, but this is a good
example of the kind of large scale efforts in the internet community
that System Administrators are routinely involved in or, at a minimum,
affected by.

You can read more at the URL above or the linked presentations and blog
posts, including e.g., https://www.isc.org/blogs/end-to-bandaids/.

Also, if you're not familiar with them, you should research these
organizations and communities in this context:
- ISC https://www.isc.org/
- DNS-OARC https://www.dns-oarc.net/
- NANOG https://nanog.org/
