SSL Certificate Health Monitoring

Blimey automatically checks the SSL certificates of all your HTTPS monitors and provides a dedicated health overview.

Certificate Health Page

Access it from the dashboard by clicking the Certificates button. This page shows:

All monitors with their SSL certificate status
Certificate issuer (e.g., Let's Encrypt, DigiCert)
Expiry date and days remaining
Validity status — whether the certificate is currently valid

What to Watch For

Expiring soon — certificates approaching their expiry date need renewal
Expired — an expired certificate will cause browser security warnings for your visitors
Invalid — mismatched domains or revoked certificates

How It Works

Every time Blimey performs a check on an HTTPS monitor, it also inspects the SSL/TLS certificate. This data is stored and displayed on both the monitor detail page and the certificate health page.

Tips

Most certificate authorities (like Let's Encrypt) support automatic renewal — make sure it's configured
Monitor your certificates at least 30 days before expiry to give yourself time to act
If you see a certificate from an unexpected issuer, investigate immediately
