Do you do on-calls from home? Here are my top tips for being non-resident. Share yours at the end. #oncall🧵
I previous worked as a critical care consultant with in-house cover 24/7. Being on-call from home has taken some adaption.
I now use the "six P's" for the things I definitely want to be called about:
Pregnant patients
Paediatric patients
Palliative patients (worried they are going to die)
Perplexing patients (uncertain diagnosis)
Political issues

I know my niche here on Twitter is narrative threads, but I wanted to take a moment to discuss something that’s very difficult for us to truly grasp.
Something firefighters grasp intuitively, but many of us struggle with.
The idea of exponential growth. 1/

Let me start with a hypothetical question.
I’ll give you the answer later.
Monday: 541
Tuesday: 704
Wednesday: 938
Thursday: 1,195
3/27: 1,589+.
These are total US COVID-19 fatalities, growing by ~30% per day.
How many by the end of April, assuming the same % growth? 2/

We’ve all heard of the idea of exponential growth, even if it wasn’t called that.
Here in the US, a bear teaches us about exponential growth as kids in school.

Started reading @Google 's #SRE book and some insights from it so far, will keep updating the thread as I finish the chapters. (1/n)
@Google The initial chapter touches upon the idea, that fixes being pushed with human-interruption need to scale linearly as the product grows/scale increases. Practicing the ideology of building systems which would in turn manage the hand holding which #syadmins do is radical (2/n)
@Google 100% uptime is probably never the right reliability target: not only is it impossible to achieve, it’s typically more reliability than a service’s users want or notice. Matching the profile of the service to the risk the business is willing to take. (3/n)
Many incidents happen during or right after the release.

Add a temporary 15min on-call rotation covering the developers who have issues in the release. Most probably they have something to do with the upcoming alerts.
