Last week, we improved the email notifications sent by Oh Dear whenever something is down or broken. They now contain links that allow you to snooze further emails, essentially "silencing" the alert for a defined period of time.
As part of our SSL certificate monitoring, we check a lot of things. The usuals, like if it covers the right domain name or if it hasn't expired are, of course, already included. But SSL certificates can get quite complex. Sometimes, SSL certificates get revoked by the issuer. When that happens, browsers worldwide stop trusting them and will throw an invalid certificate warning.
