Not 100% but 99.9%… IIRC Guild Wars 2 servers had like 1 actual outage in 11 years. They have pretty amazing structure.

Fun fact, uptime goals are measured in nines – for example, 99.9% is three nines of uptime. If that one outage lasted an entire day, and they were never down at any other time, that would indeed be three nines of uptime.

Yeah, my net admin colleagues explained that one to me a while back because the bosses were making similar uninformed demands (“this needs to never go down!” “Sure, here is how much that costs”). It was very enlightening :)

And by “never,” a lot of bosses really mean, “you’re working overtime if it goes down.” It always comes down to cost.
