A website can return a 200 OK response and still be broken.
That sounds obvious, but a surprising amount of website monitoring still focuses almost entirely on one question:
Is the server responding?
The problem is that users experience much more than HTTP status codes.
A website can technically be online while:
- navigation links are broken
- JavaScript errors prevent features from working
- a page looks broken on mobile
- SSL or DNS changes cause problems
- important SEO elements disappear
- content changes unexpectedly
- forms or interactive elements stop working
From a traditional uptime monitor's perspective, everything may still look perfectly healthy.
Uptime isn't the same as website health
Uptime monitoring is still valuable.
If your server goes down, you absolutely want to know.
But uptime is only one layer.
A more useful question is:
Is the website actually working the way a visitor expects it to?
That requires looking beyond the server response.
What should website monitoring include?
1. HTTP monitoring
The basics still matter:
- response status
- response time
- availability
2. Browser checks
A real browser can catch problems that a simple HTTP request cannot.
For example:
- JavaScript errors
- rendering issues
- broken interactions
- browser-specific failures
3. Mobile layout checks
A page may look fine on desktop and still be difficult or impossible to use on a phone.
Things like horizontal overflow, misplaced elements or broken navigation can easily go unnoticed.
4. SSL and DNS monitoring
Infrastructure changes can create problems even when the website itself has not changed.
Monitoring certificates and DNS records can help identify unexpected changes early.
5. SEO-critical checks
A website can remain online while losing important SEO elements.
Examples include:
- missing title tags
- missing meta descriptions
- canonical changes
- indexing-related changes
- broken internal links
These issues may not create an obvious outage, but they can still have a significant impact.
Why I built Did Anything Break?
I wanted a simple way to answer a broader question than:
βIs my website online?β
The question I actually cared about was:
βDid anything break?β
That became the idea behind Did Anything Break?
It combines traditional monitoring with additional checks for things such as:
- broken links
- JavaScript errors
- browser issues
- mobile layout problems
- SSL and DNS issues
- SEO-critical problems
- unexpected website changes
The goal is not to replace uptime monitoring.
The goal is to make it more useful by looking at the website from the user's perspective as well.
You can try it here:
There is a free website check available, so you can test a site without setting up monitoring first.
Final thought
A green uptime indicator is useful.
But it does not necessarily mean your website is healthy.
The web has become too complex for a single HTTP status code to tell the whole story.
Sometimes the site is online.
It just isn't working.
