We check the validity of the currently installed certificates to make sure your website will be accessible over a secure connection at all times. We do this daily and when a certificate is set to expire the next day we will switch to our Let's Encrypt certificates. 

If you've bought your SSL certificates with us we will inform you about their expiry two weeks in advance by e-mail. You can either let us renew the certificate or switch to the free Let's Encrypt certificate.
