We got tired of not having a good cheat sheet at hand to convert uptime percentages to downtime and vice versa, so we made one. Hopefully you will find it useful (I know we will).
You can download the PDF version here.
Print it out and use it as a reference when you need to quickly check how much downtime in a month 99.5% uptime actually allows for (just an example). It’s very handy. All information on just one page!
You’ll also find a smaller version inside this post, for your convenience.
