Quick answers

Is this website down checker free?

Yes. Manual checks are free with no account. Ad impressions keep it free.

Does a 404 mean the whole site is down?

No. A 404 means the server is reachable but that page is missing. The site itself is online.

What do Online, Issues and Unreachable mean?

Online: reachable and fast. Issues: reachable but erroring (5xx, 429, TLS) or very slow. Unreachable: DNS failure, timeout or connection refused.
