Do you feel the same way about SSR for non static websites vs an SPA?
SPAs are not necessarily SSR. Can you clarify your question?
What happens when your static stie infrastructure goes down?
I fear your argument is turtles all the way down.
Edit: I'll show this to my boss. I'm sure he'll get a chuckle.
I hope he does because that's a huge sign your entire management structure is super out of touch and I hope you're next DOR or incident ressponse reveals the truth.
