Regardless of why people come to your site or application, the very first experience they have with your digital brand is your DNS resolution. If it’s not performing as expected, your end-users will have a bad experience, harming your brand, your reputation, and ultimately revenue.
In this webinar Catchpoint and NS1 share insights for ensuring the site and/or app accessibility in locations around the world while discussing topics including:
How to benchmark and evaluate different DNS vendors
Tips for continuous monitoring of your full stack, including DNS resolution
How to monitor SLA metrics to hold vendors accountable
Benchmarking and selecting the right DNS vendor is only half the battle. Once it’s implemented, your vendor, like all your third-party providers, must be continuously monitored to ensure that they’re delivering the level of service they promised.
Create plans to protect revenue during high-volume sales periods. Plans include active failovers, to DNS redundancy, and even multi-DNS services.

Benchmark DNS response times. Run proactive, Synthetic tests to emulate end user interactions. Use data to compare vendors and to enforce SLAs.
LinkedIn's SRE Team runs DNS tests to isolate performance problems and identify the third-party provider responsible for the issue:
"On the DNS side, LinkedIn runs constant tests using Catchpoint’s two different DNS monitors: DNS experience tests allow Catchpoint to behave like a DNS resolver, measuring latency from an end-user perspective and providing granular performance data; direct name server tests monitor the name servers themselves, thereby providing data that ties directly to the availability of the server, and by extension, the site itself.
These DNS tests combine with one another to give LinkedIn the full scope of their DNS performance; by collecting separate data on both speed/latency and availability, the SRE team can isolate problems quickly and easily using the same Catchpoint-powered analytics engine to discover the root cause of issues and export the data to their vendors right away so that they can troubleshoot and solve the problem."
