Network SLO Compliance Calculator
Compare measured availability against an SLO and see the compliance margin plus how much downtime is left in the period.
Inputs
Availability Achieved So Far
99.9460%
Downtime Allowed in the Period
21.6minutes
Downtime Remaining
7.6minutes
Downtime Budget Consumed
64.8%
Compliance Status
At risk — burning budget 1.08 times faster than the period elapses
Step by step
Values used
Availability SLO = 99.95 %; Measurement period = 30 days; Downtime recorded so far = 14 minutes; Days elapsed in the period = 18 days
Network SLO Compliance
allowed downtime = period × (1 − SLO); achieved availability = (elapsed − downtime) ÷ elapsed.
Availability Achieved So Far
= 99.9460
Downtime Allowed in the Period
= 21.6 minutes
Downtime Remaining
= 7.6 minutes
Downtime Budget Consumed
= 64.8
Compliance Status
= At risk — burning budget 1.08 times faster than the period elapses
How it works
The allowance is fixed by the SLO and the period length, so compliance is a subtraction. Comparing the share of budget spent with the share of the period elapsed gives the burn ratio, which flags a breach before it happens rather than after. A month is compliant until it suddenly is not, and the burn ratio is what tells you to freeze risky changes while there is still budget to protect.
Formula
Network SLO Compliance
allowed downtime = period × (1 − SLO); achieved availability = (elapsed − downtime) ÷ elapsed.
- SLO
- Availability objective for the period
- burn ratio
- Budget consumed divided by the fraction of the period elapsed
Frequently Asked Questions
How is Network SLO Compliance calculated?
allowed downtime = period × (1 − SLO); achieved availability = (elapsed − downtime) ÷ elapsed. The allowance is fixed by the SLO and the period length, so compliance is a subtraction. Comparing the share of budget spent with the share of the period elapsed gives the burn ratio, which flags a breach before it happens rather than after.
Why does Network SLO Compliance matter?
A month is compliant until it suddenly is not, and the burn ratio is what tells you to freeze risky changes while there is still budget to protect.
What values do I need to enter?
This calculator takes 4 inputs: Availability SLO, Measurement period, Downtime recorded so far, Days elapsed in the period. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
