24/7 server uptime is a must!

Servers are the core elements of any IT infrastructure. It is vital that they always be accessible, both to ensure the smooth running of internal processes and the availability of your services. Server uptime, or the amount of time your servers are available to users, is one of the most important factors for optimizing network performance.

When it comes to server availability, think in terms of the “five nines.” PRTG will help you achieve the goal of 99.999% uptime.
