Certificate Authority Authorization (CAA)

CAA restricts issuance to certum.pl, letsencrypt.org; we couldn't map the serving CA (nazwa.pl Sp. z o.o.) to one of these identifiers.

Never get surprised by e-opieka.org's certificate expiring

This is today's certificate. Turn on monitoring and we'll watch e-opieka.org 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.
