What's the blast radius when your database goes down?

Mark started out on a 4k TRS-80. He had to program it in assembly language, as there wasn't enough memory to use the local Basic copy.

Throughout his career, he's oscillated between using databases and building databases. He started at Caltech and NASA, using databases to store and organize space data and chip data. Then he built databases at Oracle, including versions, 5 6, 7, and 8.

After that it was back to using databases at NewsCorp for huge student data systems. 

He built databases at AWS with Amazon RDS, then moved to Grab Taxi, the Uber of Southeast Asia, and finally back to MongoDB, where he is building again.

This week's lifeboat badge goes to Erik Kalkoken, who answered the question: In a Slack, is there a way to see all the members that is part of that channel?
