Happy New Year! We want to kick off 2021 by announcing some improvements to DNS Check.

Back in 2016, we added support for monitoring wildcard DNS records. Wildcard DNS records are used to serve requests for otherwise non-existent domain names. Today we’re pleased to announce that we’ve extended our support for using wildcards in DNS records monitoring. DNS Check now allows you to specify a wildcard (*) in place of some DNS record values, such as an A record’s IP address to indicate that any value is acceptable, but the record must exist.

We just finished refactoring the code that we use for integrating DNS Check with services like Slack and PagerDuty. It felt good to take some of the bespoke code that had accumulated over the past couple years as integrations got added in and generalize it.
