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 pdsa.com.pl's certificate expiring
This is today's certificate. Turn on monitoring and we'll watch pdsa.com.pl 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.
