Check if a website is up right now, from the edge, with header grades and a CSV.
Zovo Website Status Checker makes a live request from the edge network to each website you name. It follows the redirect chain hop by hop, reports the final HTTP status and its meaning, the total time, whether HTTPS was used, the page title, the content type and size, the six important security headers with an A-F grade, and whether robots.txt and a sitemap exist.
What you can ask
Is example.com up right now, and where does http://www.cloudflare.com redirect to?
