Certificate Authority Authorization (CAA)

CAA restricts issuance to digicert.com, globalsign.com, microsoft.com; we couldn't map the serving CA (Microsoft Corporation) to one of these identifiers.

Never get surprised by bing-exp.com's certificate expiring

This is today's certificate. Turn on monitoring and we'll watch bing-exp.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.
