Is My Website Down?
Check if your website is down, or if it's just you. Enter your URL below for an instant status check. But here's what most tools won't tell you: even when your site loads, important parts of it can still be broken for visitors — a missing script, broken styling, a checkout that quietly fails. We'll show you what to look for.

02The hidden problem
Your site says it's up — but this is what visitors see
Broken scripts
CriticalA deploy changed a file's name, so the script your site needs is suddenly missing. The page loads, but forms don't submit, buttons don't work, and checkout is dead.
Missing styling
CriticalYour styling file goes missing or is served the wrong way. The page loads — with no design at all, just raw text. The server still reports everything is fine.
Stale CDN cache
ModerateYour CDN is serving an outdated, broken version of a critical file. The main server is fine; the CDN edge isn't. Visitors in some regions get a broken site.
Third-party script failure
ModerateYour payment, analytics, or chat widget fails to load from its provider. Your page loads — but the part that takes payment doesn't work.
Broken images
LowYour image host is down or returning errors. Product photos, hero banners, and logos show broken placeholders. The page is "up" but looks abandoned.
Redirect loops
CriticalA misconfigured redirect sends visitors in circles. The homepage works fine — but your pricing, signup, or blog page is stuck looping and never loads.

How Sitewatch checks if your site actually works
- 01
We open the page
Sitewatch opens your page the way a visitor's browser would, and checks how it responds — the status, the timing, and the headers.
- 02
We check every part loads
We find every file the page needs — scripts, styling, images, fonts and third-party tools — and confirm each one loads.
- 03
We watch for changes
Sitewatch remembers what your page should look like and flags when the content unexpectedly changes — after a bad deploy, a CMS edit, or tampering.
- 04
We alert on real issues
When something fails — a missing script, broken styling — you get an alert that says what broke, why it matters, and how to fix it.

Frequently asked questions
Yes. The URL checker on this page is completely free with no signup required. For continuous monitoring that checks your site automatically and alerts you when things break, Sitewatch offers a free plan for 1 site.
Most people mean "can visitors use my site?" There are two levels: your server can be down (it errors or times out), or your server can be up while the page itself is broken — a script or your styling is missing, so visitors can't use it. Uptime tools only check the first. Sitewatch checks both.
A 200 OK just means the server sent back a page. It says nothing about whether the scripts that power your site loaded, whether your styling rendered, or whether third-party tools are working. That is the most common kind of failure — the page loads, but part of it has quietly stopped working, and it is exactly what your customers notice first.
Most "is it down" tools just check whether your server responds. This tool does that too — but it also explains what "up" doesn't tell you, and offers continuous monitoring that checks every part of your pages works.
Yes. Sitewatch offers continuous website monitoring starting with a free plan for 1 site. Unlike one-time checks, it re-checks every part of your pages on a schedule, catches problems introduced by a deploy, and sends alerts that explain what broke.
This usually means a CDN or DNS issue. Your main server might be fine, but a CDN edge in certain regions could be serving stale or broken content. Sitewatch Pro monitors from both EU and US to catch these regional failures.
