Uptime and downtime with 69 % 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 69 % uptime/availability results in the following periods of allowed downtime/unavailability:

• Daily: 7h 26m 24s
• Weekly: 2d 4h 4m 48s
• Monthly: 9d 10h 27m 1.3s
• Quarterly: 28d 7h 21m 3.8s
• Yearly: 113d 5h 24m 15s

Direct link to the page with these results: uptime.is/69

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.
