Uptime and downtime with 12 % 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 12 % uptime/availability results in the following periods of allowed downtime/unavailability:

• Daily: 21h 7m 12s
• Weekly: 6d 3h 50m 24s
• Monthly: 26d 18h 49m 36s
• Quarterly: 80d 8h 28m 49s
• Yearly: 321d 9h 55m 18s

Direct link to the page with these results: uptime.is/12

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.
