What is uptime?

Uptime is the amount of time that a service is available and operational, typically expressed in percentage.

What is SLA?

A service-level agreement (SLA) defines the level of service you expect from a vendor, laying out the metrics by which service is measured, as well as remedies or penalties should agreed-on service levels not be achieved.

How to prevent downtime?

Redundancy, monitoring and alerting are key to ensure a safe and reliable service. Odown is here to help with monitoring your critical infrastructure.

When you signup with a service vendor, you need to understand what uptime promises they guarantee and what those percentages mean. For context, an SLA of either 95 or 98 percent availability per year sounds amazing, but do you know what that really means to your business or online service? At 95%, you can expect around 18 days of unexpected downtime. At 98%, you can expect over 7 days a year of downtime. You will need to evaluate your critical business needs and say to yourself can you afford this sort of downtime?
