Uptime and downtime with 80 % SLA

2025-02-04: I am happy to announce public release of Pyng, a boring and finished uptime monitoring and alerting system.

Agreed SLA level: % (enter SLA level and hit the <enter> key)

SLA level of 80 % uptime/availability results in the following periods of allowed downtime/unavailability:

• Daily: 4h 48m 0s
• Weekly: 1d 9h 36m 0s
• Monthly: 6d 2h 5m 49s
• Quarterly: 18d 6h 17m 28s
• Yearly: 73d 1h 9m 50s

Direct link to the page with these results: uptime.is/80

The SLA calculations assume a requirement of continuous uptime (i.e. 24/7 all year long) with additional approximations as described in the source. uptime.is was originally implemented in newLISP, which had powered uptime and downtime calculations for more than a decade.
