Certificate Authority Authorization (CAA)

CAA restricts issuance to sectigo.com; we couldn't map the serving CA (Pionica) to one of these identifiers.

Never get surprised by pionica.net's certificate expiring

This is today's certificate. Turn on monitoring and we'll watch pionica.net 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.
