Amazing! In my opinion, this is the most resourceful video with a lot of content easily comprehended within just 13 minutes. Would love to see more of these... :)
Usually its not that there is complete outage for x mins/sec depending on availability target but rather some number of Service queries result in failures all throughout the time span. This actually requires availability to be measured wrt. to number of failed queries vs successful queries.
Government websites' downtime is approx 10 days. Eventhough the user experience is frustratingly bad, we are left with no choices. 😢 Their usage graph is exponential post the downtime even if the system upgrade decides to mess you up even more.
I wouldn't say that if the cache is down then it's alright, unless it restarts really quickly, you might get a thundering herd of requests to the main db, which might make it run out of resources thus causing a big problem. Other than that, great video 😊
Love your content. Your wisdom and knowledge is immense.

Great video, been watching your channel for years. Small suggestion: improve audio using a mic.

Good point!
What are the moving parts? Some example plssss
how can i calculate no. of server replicas i need, if i have 1M users with peak hours 10 - 11 pm serving 80% traffic?
Great thanks
You missed a level, Government websites- Availability ~ 70%
exam result websites, Availability ~ 7%
Scaling the database ia the hardest problem you will face.
