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

SLA level of 98.27 % uptime/availability results in the following periods of allowed downtime/unavailability:

• Daily: 24m 55s
• Weekly: 2h 54m 23s
• Monthly: 12h 38m 15s
• Quarterly: 1d 13h 54m 44s
• Yearly: 6d 7h 38m 55s

Direct link to the page with these results: uptime.is/98.27

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.
