Welcome to Dyn’s Dynamic Steering FAQs!


What is Dynamic Steering?

Dynamic Steering is the first solution that pulls together all aspects of Dyn’s Internet Performance Platform. It combines our world class DNS solution with granular insights into the performance and reachability of CDNs, Cloud providers, data centers, and global markets.


Where do you get your data?

The data powering our Dynamic Steering primarily consists of Real User Monitoring (RUM) data. This comes from taking detailed timing measurements of the latency end users experience when requesting various internet assets. This provides accurate measurements of CDN, Cloud, and data center assets that can be used to perform steering decisions.


What is a RUM Beacon?

A RUM Beacon is a small piece of software you add to your website. This provides a way for us to monitor performance and availability data for individual user connections to your site. For more information on a RUM Beacon, please see our RUM Beacon Getting Started Guide.


How do RUM Beacons work?

The Dyn RUM Beacon measures monitored assets from the perspective of end-users, providing insight into how CDNs, Cloud, and data centers are performing to access networks around the world.


Will adding a RUM Beacon slow down my website?

No, the RUM beacon is set up to load and fire tests asynchronously which will allow your page to load fully before beginning any tests.


What data is collected and stored?

Stored performance and availability data includes limited and non-personally identifying data related to end-user interactions with your site. These data elements are the client IP (anonymized to maintain privacy), User-Agent, and URL of the page navigated to.


Can I manage my policies using an API?

Yes, all UI functionality is available using the Dynamic Steering API.


What rules are available for Dynamic Steering policies?

Availability Rule – Excludes all answers that report as down.

Performance Rule – Returns the XX fastest answers for the policy, where XX is a user configurable number of answers.

Max Count Rule – Returns a maximum count of XX answers for the policy, where XX is a user configurable number of answers.
