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 98.7 % uptime/availability results in the following periods of allowed downtime/unavailability:

• Daily: 18m 43s
• Weekly: 2h 11m 2.4s
• Monthly: 9h 25m 5.9s
• Quarterly: 1d 4h 15m 18s
• Yearly: 4d 17h 1m 11s

Direct link to the page with these results: uptime.is/98.7

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.
