Uptime Monitoring: Definition and How it Works

In today’s digital age, website owners all face a few common problems: Website downtime, expired SSL certificates, and improperly working ports. According to a study done in 2021, it affects about 71% of companies. The worst part is that most of the time they don’t even know that they experience downtime. 

Fortunately, there is a solution out there for all of these companies: Uptime monitoring. In this blog post, we’ll explain what it is and how it helps you save time and money. Stick around to learn what a vital role these indicators play in your website’s accessibility. 

What is Uptime Monitoring?

Simply put, uptime monitoring is the process of monitoring to see if a website or an app is working the way it should. Website uptime is the time your website works how it should, meaning that your website or app is running correctly. 

The purpose of uptime monitoring is simple: to ensure that you know when your website is experiencing downtime.  

How does Uptime Monitoring work? 

The process of uptime monitoring in terms of technicalities works by sending HTTP requests to a URL. The requests are sent at regular intervals to make sure that the website is actually responding. Most of the time, HTTP (POST) requests or GET requests are used to make sure that it responds. 

  • GET request: This type of request is used to request data from a very specific place or resource. It’s more of a safe way, meaning that the data can be received as many times as you want without different outcomes in return.
  • POST requests: Data is passed on inside the body of the HTTP request during a POST request.

What are the different types of Uptime Monitoring?

There are a few different types of uptime monitoring. These can be as different as an HTTP to a FTP. If you’re not sure what these are, we’re here to explain:


The first type of uptime monitoring is HTTP monitoring. HTTP monitors the uptime of HTTP (HyperText Transfer Protocol) servers. It checks if your website is up and running and how fast it is responding.


HTTPS is for websites that use secure connections such as SSL/TLS. It checks the certificate of your website validity along with your server’s uptime.


In the simplest sense, ping sends an ICMP (internet control message protocol) echo request to your server to see if it’s responding. It also checks how fast the server responds. It’s a simple way to check if a server is being reached.


TCP or Transmission Control Protocol monitors the uptime of any service (like SSH, FTP, SMTP, etc.) by showing that there is a connection to the server on the specified port. TCP also falls under port monitoring but is not the only port that can be monitored. 


Monitors the uptime of UDP (User Datagram Protocol) services. It sends a UDP packet, which is a core communication protocol to the server and waits for it to respond. It’s almost like a man who takes a letter to a house and then waits for the person to respond by writing another letter.


This is a type of top-of-port monitoring. It sends out continuous checks to monitor the status. Best of all, the uptime of your DNS (Domain Name System) server is one of the things that it checks. It also verifies that the server is correctly translating domain names into IP addresses.


This monitors the uptime of your POP3 (Post Office Protocol version 3) email servers. It logs into the email server, performs a status check, and then logs out.


It monitors the uptime of your SMTP (Simple Mail Transfer Protocol) servers. It checks the server’s ability to send mail.


FTP monitors the uptime of your FTP (File Transfer Protocol) servers. It logs into your FTP server, and then performs a directory listing (a type of Web page that lists files and directories that exist on a Web server), and then logs out.


IMAP monitors the uptime of your IMAP (Internet Message Access Protocol) servers. It logs into the email server, and then checks the status of the mailbox, then it logs out.

What are the benefits of Uptime Monitoring?

Early Downtime Detection:

In the digital age, a fully operational website is a non-negotiable asset for businesses, big and small. Downtime is a battle that every website owner must face time and again. Uptime monitoring is often used as a way to ensure organizational success. By using advanced uptime monitoring services, businesses gain real-time insights into their website’s performance. This way, they can detect downtime the moment it happens. These almost instant notifications mean that you can act immediately to minimize downtime and reduce its impact on your business.

Positive User Experience:

User Experience (UX) has a direct impact on customer satisfaction online. There are a few things that factor into creating a positive UX, including fast page loading speeds, easy and simple navigation, and content accessibility. Uptime monitoring serves as a guardian, ensuring your digital presence consistently meets user expectations. It provides granular analytics regarding user interactions, helping to sustain an always-available website. Remember, a website that fails to load is the ultimate UX breakdown. With uptime monitoring, such a scenario is rapidly detected, allowing you to maintain an inviting digital portal that consistently welcomes your audience.

Increased revenue:

The relentless pursuit of uptime is more than technical – it’s financial. Downtime has a direct negative impact on revenue as potential customers experience service interruptions. Imagine a user is about to convert – whether it’s signing up, making a purchase, or clicking that “subscribe” button – and the website fails. That lost opportunity translates directly into lost income. Uptime monitoring is your barrier  against these issues, making sure that your website remains a robust, revenue-generating platform.

Detailed reports:

The way that uptime monitoring works is by sending data to and fro, where it’s then saved for future use. It can then be accessed and you can view all of the findings. With a detailed report of your website’s data, you can make more informed decisions about what to do next and understand how your website is functioning. You can also pick up on potential issues and be in a better position to be proactive and take action. 

Detect intrusions:

Security is a cornerstone of digital trust between you and your visitors.Uptime monitoring can play an important role in safeguarding your website from cyber threats and hackers. Getting alerts when your website faces an attack is invaluable, allowing you to take immediate action and protect sensitive information. With uptime monitoring, you’re not just keeping an eye out for downtime; you’re staying one step ahead of potential security breaches.

Diagnosing and resolving issues:

Uptime monitoring doesn’t just let you know when your site is down – it provides invaluable insights that help you understand why it happened to begin with. These real-time diagnostics allow you to react immediately, making sure that technical glitches are resolved quickly and effectively. 

Boosting overall performance:

When it comes to website management, fewer problems lead to better uptime, and more uptime means better performance. By taking advantage of advanced uptime monitoring services, you’re saying”yes” to a smoother, more reliable website. Your users will notice and appreciate the improvements in performance and user experience.

Why is Uptime Monitoring Important?

Imagine this: You hire someone to refresh a page and check that all your pages are working. They do this the whole day. 

Yes, you will know when your website is down, but it will cost your business valuable time and money in the process. 

For website owners and businesses, uptime monitoring isn’t an option—it’s a necessity. Integrating a comprehensive uptime monitoring system into your digital strategy ensures you’re always delivering the best possible online experience while protecting and growing your revenue. Keep these benefits in mind as you aim for the pinnacle of digital excellence: an always-on, high-performing website that delights users and drives business success.

Best Practices for Uptime Monitoring

  • Monitor Critical Services: It’s important to monitor critical services to ensure the uptime and functionality of your website. This is best done using monitoring tools, alerts, and regular checks.
  • Regular Maintenance: This includes updating checks, verifying alerts, and reviewing notification settings.
  • Proactive Monitoring: Uptime monitoring helps you stay ahead of any network issues, ensuring that your business remains online and operational 24/7.
  • Using Uptime Monitoring Tools: A monitoring service or tool  like Tethered makes automated HTTP requests to your website or application’s server at preset time intervals. If the server responds with a 200 response code, your site is up and running. But, if the monitoring tool receives an error code from the server, it means your website or page is down. The monitoring tool will then send downtime alerts to report the incident.
  • Incorporate Active Monitoring, Real User Monitoring, and SLA Management: This will help you get an all-round view of what is going on within your website.
  • Reporting: Take advantage of built-in status pages that display response time and automate status updates depending on the feedback received. 

Most importantly, the goal of any website should be to maintain as close to 100% uptime as possible. Downtime, even for a few minutes, can result in financial losses, frustrated customers, and a damaged reputation.
