There is nothing worse then your website going down and you hearing about it from someone else. As a CDN provider, we take downtime very seriously. Downtime could affect your company or brand in a lot of different ways such as lost sales, a bad first impression for new customers, customer loyalty, and your overall reputation. Today we want to dive into the top 15 website monitoring tools to help you stay on top of your website’s uptime and ensure that your site is online and running 24/7 without a hitch.
“I think that all services will have downtime. No matter how much you prepare, have redundant systems, or audit, there will periodically be a black swan event that is completely unlike whatever you’ve experienced before. It even happens to Google!” – Matt Mullenweg
When it comes to downtime, every second counts. Back in March 2016, Amazon.com went down for about 20 minutes. Internet Retailer estimates that a 20-minute outage cost Amazon about $3.75 million. Again, these are all estimates, but you can see how things begin to quickly add up. Especially when it pertains to large e-commerce sites. As a CDN provider we have it easier because we can route your requests to another edge server if one goes down. But with your origin server, most of the time you have a single point of failure. Below are just a few ways website downtime could affect you:
According to research from IDC, among the Fortune 1000 companies, the average total cost of unplanned application downtime per year is $1.25 billion to $2.5 billion. Another survey, from Siemens Building Technologies, shows that 33% of organizations don’t even know the impact of one day’s downtime on their business.
Here is a simple formula you can use to calculate how much profit you might lose if your website goes down:
Yearly Revenue / Business Hours x Website Impact to Sales %
And if you are solely an online retailer or e-commerce site, that impact % could very well be close to 100%. Which means every second counts!
2. Brand Reputation
What is the very first thing people do today when a website is down? They go straight to Twitter and Facebook to voice their frustrations. This can be very bad for brand reputation, as you don’t want potential new customers seeing this activity on social media. Below is an example of just a few of thousands that headed to social media when Amazon went down earlier this year.

Here’s something I don’t think I’ve ever seen: Amazon is down.
— Dan Goodin (@dangoodin001) March 10, 2016
Social media can be a very effective tool for companies and brands today, but it also forces you to be very transparent. There isn’t anywhere to hide on the internet.
3. Dissatisfied Customers
Once you have customers, you don’t want to lose them! If your website goes down, especially for SaaS companies with application logins, this can be a disaster. Just like with web performance, customer’s only have so much patience before they might think about switching to another service. For e-commerce sites, a customer might simply switch to your competitor and do their shopping there instead. So it is very important to maintain good uptime and keep your current customers happy.
4. First Impression for New Customers
Brian Tracy, a worldwide bestselling author, sums it up quite nicely:
“A first impression says everything. Perhaps the simplest example of the application of this rule, that everything counts, involves your image or appearance. You’ve heard it said that you never get a second chance to make a good first impression. The fact is that when you first meet a person, he makes a judgment about you in approximately four seconds…”
You can almost guarantee that if a new customer is looking to purchase what you are selling and your website is down, they will never return. So make a good first impression! And while your at it, ensure your website loads fast. Check out our 18 tips on website performance optimization.

Perhaps you want to monitor your CDN provider as well as your web host? Any of the tools and services above can easily be used as a CDN monitoring tool. Remember though, a content delivery network (CDN) is all about reliability. For example, with KeyCDN, if a POP or edge server happens to go down, we automatically route the additional requests to the next nearest POP. This ensures that your content delivery never stops. Most CDN providers all have fail-overs in place in case of a catastrophe.
Monitoring your uptime is very important, so a tool like one of the ones above can come in very handy!
