Certificate Authority Authorization (CAA)

The serving CA (Let's Encrypt) is not among the authorities this domain's CAA records authorize (sectigo.com). This can indicate a misconfiguration or an unexpected issuance.

Never get surprised by ing-host.jp's certificate expiring

This is today's certificate. Turn on monitoring and we'll watch ing-host.jp continuously, notifying you the moment anything moves across all three signals:

Certificate monitor showing the issuer, expiry date, chain status, fingerprint, covered names, and a history of a rotation and an expiry warning

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, CNAME, TXT 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.
