TXT record graffiti successfully sprayed

~/workspace/infrastructure ? dig -t TXT graffiti.scottmuc.com +short
"Macbook air repaved on Christmas day of 2020!"

I wonder how many TXT records I can create?

Had issues installing Ledger Live so disabled that for now. From what I can tell, downloading the installer is severely rate limited. Here is the curl that I can see.

Completion Notes

I'm going back to monthly repaving. After doing quarterly repaves this year, I was left feeling less confident with my repave ability. It didn't feel as routine as it's supposed to. Learning how to create GitHub issue templates may reduce the friction in getting started.
