Translating Downtime into Percentages
Service providers love to promise high uptime percentages like "99.99%". This calculator helps you understand what those numbers mean in practical terms.

Frequently Asked Questions

Network uptime is the percentage of time that a network or service is accessible and operational. It's a key measure of reliability, often included in Service Level Agreements (SLAs) from ISPs and service providers.
What is a good uptime for a network?
For critical business operations, an uptime of 99.99% ("four nines") or higher is often the standard. This translates to less than an hour of downtime per year. For home internet, 99.9% ("three nines") is generally considered very good.
