Consider yourself lucky that you’ve never been the victim of a fiber cut. But what about if the power to your house goes out? Or what if your server blows the power supply?

My entire point is that you have no redundancy in your system and you also aren’t big enough to have any pull with the vendors who can fix these types of outages so you’re basically at the mercy of your providers with no recourse.

That’s why these systems are built the way they are.

And generally four nines is considered the gold standard these days. I can tell you for sure that both Netflix and Ebay would lose money anytime they drop below four nines because I have at some point been responsible for both. You’re correct that Reddit has a lot more leeway and outage time before they start losing money but not that much leeway.
