Uptime and downtime with 99.85 % SLA

The Uptime Challenge! Is there a programming language or some fancy old or new technology you'd like to try/learn, but lack that special useful something to use that tool on? Well, I've created an informal spec of the uptime calculator and invite everyone to participate in the #UptimeChallenge. The goal of the challenge is to implement the functionality in the whatever way you'd like (simple, complex, fast, slow, elegant, ugly, baroque, esoteric, client-server, service oriented, serverless, cloud native, whatever) while having fun at the same time. Once done, publish your work on your code forge of choice and tag it with #UptimeChallenge. The uptime challenge goes on as long as code gets written. Have fun!

The SLA calculations assume a requirement of continuous uptime (i.e. 24/7 all year long) with additional approximations as described in the source.
