1% of a year is 3.65242199 days.
So on the extreme end 37signals could be down for over 3 days in a single bout and still have 99% uptime. 3 days downtime is serious.
However, this case is unlikely.
Also unlikely is a scenario where they are down for the same time each day---14.4 minutes @ 99% uptime.
Its most likely that they're down for a few minutes here and there across the day during working hours, which makes for an incredibly frustrating experience. You can never just click a button and know your form will be submitted.
- jshen 16y agoYes, but there are a some more nuances. I'll bet a fair amount of downtime is scheduled, and would be scheduled for low usage periods. Second, most services I've ever used with an SLA for n sixes hasn't actually lived up to that SLA. Instead they offer you a prorated charge for that month or something similar. What people promise in an SLA and what they deliver are very different things. I'd be very interested in some stats about historic uptimes for similar sites. Also, how much more are you willing to pay for an extra 9 of uptime?
