Uptime, nines, and hosting

What is Uptime?

Uptime is the most important single metric you can use to measure the performance of your website hosting company. It is a representation or percentage your website is up and available for your visitors. Availability is the same as uptime. Both metrics are often measured in “Nines.”cincinnati-server-hosting-uptime

Let’s see how the “nines” translate to uptime for 30 day period:

  • 1 nine would be 9% (horrible) – I didn’t waste time even calculating this.
  • 2 nines would be 99% (still horrible) – This is 7+ hours of downtime a month
  • 3 nines would be 99.9% (getting better) – This is 40+ minutes of downtime a month
  • 4 nines would be 99.99% (our basic package) – This is 4+ minutes of downtime a month
  • 5 nines would be 99.999%  – This is 3 seconds of downtime a month

Service Level Agreements (SLA)

Some hosting plans provide a Service Level Agreement. It states the guaranteed level of availability. If we don’t deliver the specified uptime level, you will be entitled to refunds or hosting credits.

I want the most uptime

Typically, hosting plans with the most uptime also cost the most. Most business should seek a middle ground where the uptime is adequate and the costs are affordable.

100% Uptime

No web hosting company has 100% uptime. They may have a 100% uptime guarantee, but that just means you’ll get a credit if you actually report it. The burden is on you to report the downtime  and request a credit. if you never notice the 5 seconds of downtime, and you never report it, you’ll just end up paying an outrageous monthly cost and get very little in return.

If your website is down more than 4 minutes a month, you should switch your web hosting provider to AllPro Technologies.
