Identifying the EC2 instance being shut down by AWS

Got an email recently from AWS saying one of our EC2 instances was being shut down due to underlying hardware degradation. I needed to quickly find out the impact and alert the engineer who owns this instance. I was clearly NOT the right recipient of this alarm.

You might think this would've taken me calling/emailing my head of engineering, and the engineering team scrambling to figure this out.

But instead, I turned to our own J1 instance for help. One full text search and a few seconds later, I had the full context, found the owner and alerted him.

This EC2 instance wasn't in production. If it was, we just avoided a production outage in minutes.

One of the many stories of how we use J1 at J1.
