No matter if you manage a complex web infrastructure or run a small business website – these services have you covered when it comes to keeping it accessible 24/7 for users.

What is Uptime?

Before we jump in and examine this list, it is essential that we define some key terms. Uptime refers to the amount of time your website and its contents are fully operational and available – it is typically measured as a percent; so, for instance, if it is only up 99% of the time then that translates to over 7 hours of downtime each month.

Downtime occurs when part or all of a service ceases operating, leading to disruption and potential client loss. Each downtime should be recorded, evaluated, and reported upon – that’s where uptime monitors come into play.

Monitoring goes beyond simple on/off systems; website performance issues are far more subtle. Your website could still be online but still perform poorly due to location-related problems, slow load times and ineffective optimization techniques, or peak hour failures – all data that is crucial for its success and could determine whether you make it past competition or not. Relying on external website monitors allows you to avoid failure where others have fallen short and instead avoid making that journey in the first place.

Customer Trust: Customers trust websites with consistently available pages, so ensuring high uptime helps foster that relationship and build it further. By doing so, your audience becomes more likely to return and engage with your content or services.

Compliance: Certain industries and organizations require meeting compliance regulations with regard to uptime. Monitoring helps you meet this standard while also reducing potential penalties.

Data Analysis: Uptime monitoring tools often provide helpful data and analytics about your website’s performance, giving you information to make more informed decisions on infrastructure upgrades or optimizations.

How Do You Monitor Website Uptime?

Given that no business is immune from downtime, it is imperative that they monitor their website closely. Monitoring is simple – simply check it every minute to see whether it works as expected; not only should the pages load quickly but all components should work as intended – searches, buttons, slideshows and shopping carts. Furthermore, all business should examine their websites from different locations as part of this ongoing evaluation.

If your company is large enough, consider creating a department dedicated to this issue. This team should send requests out to resources in order to test if they respond and communicate with components to assess whether everything is operating smoothly.

However, for small- to mid-sized businesses, non-profit organizations, or personal blogs with limited time and resources available, this approach may not be viable; there’s always the risk that you miss some vital details.

Therefore, site tracking services provide the solution; they automatically ping resources, interact with components mimicking human behavior, check protocols, provide comprehensive reports, and notify their owner accordingly.
