So, in the spirit of “cattle, not pets”, my goal is to decommission the Linode VM and move into AWS, and automate as much as I can while doing it. Rather than put a whole bunch of time into investigating the root cause, I know the system needs an entire OS upgrade and we’re running a bunch of services that are no longer in use like IRC and Jabber servers – these have been replaced, at the cost of our freedom-as-in-speech, with Slack. In my experience this can mean a variety of things, ranging from “your site got quite a few visitors in a short timeframe” to “the backup process is going wonky” to “someone hacked your box and is trying to use it to mine cryptocurrency.” One of the recurring messages has been a “high CPU” notice from Linode every few days. I’ve been trying desperately to catch up on my personal email these past couple months, since it’s rare (with the addition of two babies to our family) to have large uninterrupted blocks of time in which to hack.
