Frequently Asked Questions
How does the status checker work?
Our service performs multiple checks to determine a website's status:
- Validates the domain name
- Checks DNS resolution
- Verifies domain registration
- Attempts to connect to the website
- Measures response time and analyzes the response
What do the different status colors mean?
What URLs can I check?
You can check any public website. Enter the domain name (e.g., "google.com") or the full URL (e.g., "https://google.com/search"). The service will automatically format the URL correctly.
Understanding URL Components
A URL (Uniform Resource Locator) consists of several components that define how to access a resource on the internet. Here's a breakdown of each part:
https://www.example.com:3000/path/to/page?query=value#section
Scheme (Protocol)
https:// or http://
Defines how the browser should communicate with the website. HTTPS is secure and encrypted, while HTTP is not.
Subdomain
www. or blog. or mail.
An optional prefix to the domain name that can specify different sections or services of a website.
Domain Name
example
The core name of the website, usually representing the brand or organization.
Top-Level Domain (TLD)
.com or .org or .net
The extension that indicates the type of website (.com for commercial, .org for organization, etc.) or country code (.uk, .jp).
Port Number
:3000 or :443 or :80
Optional number that specifies which port to connect to on the server. Standard ports (80 for HTTP, 443 for HTTPS) are usually omitted.
Path
/path/to/page
Specifies the exact location of a page, file, or resource on the website.
Query Parameters
?query=value&name=john
Additional data sent to the server, often used for searches, filters, or tracking.
Fragment (Anchor)
#section
Points to a specific section within the page. This part is processed by the browser and not sent to the server.
When using our status checker, you can enter a URL with or without the scheme, subdomain, or port. Our service will automatically format it correctly before checking the website's status.
