This does assume that nothing is getting broken along the way.

Taking 45 days is probably more about caution and resolving issues systematically rather than pushing a big button and hoping you don’t cause issues.

I’d expect them to have thousands of microservices - and you only have to find a way to break one to cause big issues.

Regular random crashes should be exercised regardless at Facebook scale. Not being resilient to that would be very unprofessional.
