Ask HN: What is your company's on-call rotation like?

Also looking for readings on best practices.

Curious about your company's on-call for details about:

* expected duties (only answer on-call, do other work, etc)

* how deep does your on-call dive into code to fix, vs triaging, patching, and creating follow up work to fix permanently?

* priority order of work (on-call tickts vs regular work vs existing on-call tickets vs special queue of simple tasks)

* what happens when the current on-call can't complete in time?

* how do you manage for other teams' risk? (ie their api goes down, you can't satisfy your customers)

* any other tidbits
