Dynatrace is implementing a configuration change that involves adding new public IP addresses to enhance the delivery of alerts from its SaaS platform, which is critical for monitoring web applications. This change, effective in the first week of March 2020, requires users to update their firewall rules by adding these new IP addresses to their allow list to prevent incoming alerts from being blocked. The update affects all users who have configured any alerting channels other than email and is communicated through in-product notifications, representative communications, and release notes. Failure to adjust the firewall configuration as instructed could result in an alert outage, impacting the timely response to performance issues detected by Dynatrace.
