SLA Deep Dive
How Verizon Business actually measures uptime.
A 99.99% SLA sounds impressive until you read the fine print. Here is how it is instrumented, reported, and enforced on a Verizon Business circuit.
99.99%
Monthly availability target on Business Ultra fiber — roughly 4 minutes of downtime per month
99.999%
Availability on Dedicated Internet Access and Private 5G — under 30 seconds per month
4 hr
Mean Time to Restore target for hardware-caused fiber outages
<15 min
Proactive NOC notification from first detection of customer-impacting degradation
The three metrics that define a real SLA
Availability is the percentage of minutes in a calendar month that the circuit was able to pass traffic between the demarcation point and the nearest Verizon backbone POP. Mean Time to Restore is the committed turnaround from ticket open to verified service restoration. Jitter and packet loss thresholds govern the quality of service during uptime — a circuit can be technically up while still failing a real-time workload.
What triggers a credit
When any committed metric is missed in a given month, the system generates an automatic credit posting equal to a published percentage of the monthly recurring charge. No claim form. No manager approval. The credit appears on the next invoice with a reference to the incident ticket that caused it. This is how you know the SLA has operational teeth.
How outages are classified
Outages fall into three buckets: customer-caused (bad CPE configuration, power loss at the premise), carrier-caused (fiber cut, equipment failure), and force majeure (natural disaster, third-party backhoe). Only the middle category counts toward SLA penalties, but the NOC will actively work restoration across all three categories with the same urgency.
