Uptime and downtime with 1 % SLA

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

[ simple / flexible / compare / reverse / about / API / monitoring ]

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

SLA level of 1 % uptime/availability results in the following periods of allowed downtime/unavailability:

• Daily: 23h 45m 36s
• Weekly: 6d 22h 19m 12s
• Monthly: 30d 3h 10m 49s
• Quarterly: 90d 9h 32m 26s
• Yearly: 361d 14h 9m 42s

Direct link to the page with these results: uptime.is/1

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.
