Good advice in this article, especially the bits about communicating every 15-30 minutes depending on severity. Comms are invaluable for timeline/postmortems.

Good advice in this article, especially the bits about communicating every 15-30 minutes depending on severity. Comms are invaluable for timeline/postmortems. Also, for secondary/shadow on-calls, you will need to remind the primary to loop you in, as they will be busy. Try not to be on-call too often, but also try not to be on-call too little. You need exposure to the latest types of events happening and don't want to get rusty. Once every 1.5 months is a good balance for me.
