FAQ
Frequently Asked Questions
What does a 200 OK status mean?
A 200 OK status code indicates that the request succeeded and the website server is online, active, and returned the requested page.
Why does a website show as 'down' for me but 'up' in the checker?
This discrepancy (sometimes called 'just me or everyone') happens due to local network issues, DNS caching, ISP routing blockages, or local browser plugins.
How does the tool verify status?
The checker makes standard web calls to fetch headers and returns availability indicators based on returned HTTP codes.
