How many 'nines' do you actually need versus pay for? · Datacenter Talk

I checked once. OVHcloud Vint Hill, 99.91% over 2 years. I opened ticket. They said "your monitoring tool is wrong, use ours." Their tool said 99.99%. I said "show me the raw data." They closed ticket.

Now I use both and report the worse number to myself. This is called "management."

What's your acceptable downtime per year? · General Discussion

Failure is free

This is the real insight of the thread. Not nines. Cost of failure vs cost of prevention.

For hospital, failure cost is lawsuit and death. For warung web, failure cost is one WhatsApp.

Different math. Same engineering.
