Guides for when a website won't load
Short, practical routines for the moments after a failed check, or a passed one that still leaves you staring at an error. Each guide works on its own; start with the first if you are not sure where the problem sits.
Which guide to open first
Start with the checker on the homepage. If it reports the site as unreachable, the fault is on the site's side and none of these guides will bring it back; waiting is the honest answer. If it reports the site as reachable while your browser still fails, the problem sits somewhere between you and the site, and the first guide in the list narrows that down in about five minutes.
A browser message that names a certificate or a privacy warning belongs to the security exception guide, not the DNS one. A number such as 403 or 503 in the error page points straight to the status code guide.
