What we check
Three things decide whether a domain is reachable, trusted, and yours. We check all three in one scan.
🌐
DNS propagation
Whether your domain resolves to the right server, everywhere in the world.
Why it matters: if DNS hasn't propagated, some visitors can't reach your site at all.
🔒
SSL certificate
Whether your HTTPS certificate is valid, who issued it, and when it expires.
Why it matters: an expired certificate shows every visitor a full-page security warning.
📅
Domain expiry
When your registration lapses and whether auto-renew is on.
Why it matters: a lapsed domain can be bought by someone else — and is hard to recover.
