◉ Uptime & speed check
One real request from our server: status code, DNS / connect / TLS / TTFB / download timing, redirect chain and response size.
Could not check https://expired.badssl.com/. TLS error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1010)
What we check
One real GET from Vigil's servers: HTTP status, DNS lookup, TCP connect, TLS handshake, time to first byte and download time, every redirect hop with its status, the server header and the response size.
"It works for me"
A site can be up from your office and down from everywhere else: DNS, firewalls, CDN regions. A check from outside is the only one that counts.
