Certificate Authority Authorization (CAA)
CAA restricts issuance to letsencrypt.org, sectigo.com; we couldn't map the serving CA (Your Company) to one of these identifiers.
Never get surprised by in-prague.com's certificate expiring
This is today's certificate. Turn on monitoring and we'll watch in-prague.com continuously, notifying you the moment anything moves across all three signals:
Uptime
We visit the site from multiple regions worldwide and email you within minutes if it goes down, with a per-region breakdown so a real outage stands out from a regional blip.
DNS changes
We watch NS, MX, CAA, DNSSEC, CNAME and A/AAAA records, and identify the host, network, and ASN behind them, so a real migration or hijack stands out from routine noise.
TLS certificate
We warn you 30, 14, 7, and 1 days before it expires, and flag it if the issuing authority changes or the certificate is unexpectedly replaced.
Free for your first domain: uptime, DNS, and certificate together. No credit card.
