Intelligent traffic steering has improved uptime and now needs simpler policies and support
The best features IBM NS1 Connect offers include the authoritative DNS filter chain, traffic steering policies, and endpoint health monitoring, along with its API-first automation and DNS reporting, which are all some of the most valuable features. Out of those features, I find myself relying on the traffic steering policies the most because we detect the endpoints and steer new DNS responses towards healthy alternatives. This is very helpful because whenever there is a massive amount of requests coming into the region or to the server, and for a better user interface and customer experience, we should not show the user that the server is down. We can reroute the request to the server nearest to that region, making it an important capability. The authoritative DNS ensures DNS queries for domains and reliable DNS resolution are essential for users, particularly to discover application endpoints, but it alone does not guarantee this. The API-first automation automates DNS configurations and changes through APIs and infrastructure as code workflows, reducing repetitive manual work and the risk of human error. The DNS reporting and analytics help teams understand query volume, traffic distribution, and unusual behavior under the support of troubleshooting and capacity planning.

It's easy to use and set up, but I've faced performance problems
I have experience with Quad9 and most other filtering solutions. Quad9 was working well initially, but it started slowing, so I switched to OpenDNS. I recently checked Tom's Hardware, an IT review site, and read a review of seven DNS filters. Open DNS was ranked the fastest, and Quad9 was second. Google was on there too, but they said it didn't filter enough.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I couldn't recommend a better product than NS1 for managed DNS and CDN load balancing right now."
"The auto DNS traffic routing helps during deployment or incidents by providing more reliability and faster performance."
"The best benefits of using IBM NS1 Connect are the performance and availability of the product towards the cloud, and when comparing the performance with other products, I believe it is above par, as it is really helpful and gives me at least a 20 to 30% improvement in functionality."
"IBM NS1 Connect has a positive impact on my organization, as I believe it improves security, availability, and DDoS attack mitigation because it detects failures and automatically redirects users to healthy resources."
"NS1 solution has many more features and it works faster than any of the other solutions."
"The authoritative DNS ensures DNS queries for domains and reliable DNS resolution are essential for users, particularly to discover application endpoints, and the API-first automation automates DNS configurations and changes through APIs and infrastructure as code workflows, reducing repetitive manual work and the risk of human error."
"In general, I would say that this has been the easiest solution to manage and implement."
"The real reliability and uptime of the global Anycast service are 100%, which we really appreciate."
"Setting up Quad9 is straightforward if you know what you're doing, and it's easy to use overall."
"The most valuable feature of Quad9 is that it is a free solution."
 

Cons

"Our experience with customer support has been mixed; while some team members are really helpful and responsive, there have been instances where responses to complex technical issues are slower because they need to evaluate and provide support."
"We use our client in our infrastructure to communicate with NS1. This client is a bit complex in the way that it is set up. NS1 has their own client solution that you can deploy into your platform to do this, but even that is a bit complex. So, I would like a very simple, thin, light API agent that we can deploy into our platform to communicate with NS1. That would be welcome."
"IBM NS1 Connect could be improved with more intuitive dashboards, clearer troubleshooting guidance, and more detailed real-time visibility into DNS performance and traffic routing."
"When we first deployed, we flipped the switch, and it didn't work as well as we expected. It wasn't a complete outage, but we had issues in some places with some customers. The NS1 team went out of their way to resolve it on Thanksgiving. We have a post about it on our blog. We called it "Black Thursday.""
"The Filter Chain simulation is really good in the UI, but it would be nice to have something similar in the API so that we could simulate and test things before we deploy them."
"I am not overall satisfied with the license and cost for IBM NS1 Connect because my pre-sales team interacts on that part regarding pricing."
"I believe IBM NS1 Connect can be improved in several ways. The main concern I identified is the cost, which is higher than other solutions despite its uses."
"I would like to see the UI updated to allow me to do finer searches. I would also like to have the ability to get reports that can sort based on various metrics. For example, I would like to be able to say, "Show me the top 10 records by total queries" in an easy-to-digest format."
"Quad9 could improve by having more free features, such as custom DNS filtering."
"It used to work fine for all the devices, but it started to slow and become non-responsive. I would have to reload the page two or three times before all the pages loaded. With OpenDNS, I only need to load the page once."
 

Pricing and Cost Advice

"Everything can always be cheaper, but as it is today the pricing is fair."
"We pay about $30,000 a month. We used to pay about $20,000 with Dyn every month, for lower volume than we're doing right now, but it had none of the features that we have available with NS1, so it was worth it for us. It seems competitive for us, given that we're doing 4.5 billion requests."
"NS1's pricing is much more aggressive than its competitors in the market and you get more value out of what you pay for it."
"The cost of this product is one of the reasons that we chose it."
"From a cost standpoint, it's certainly not the most expensive out there, and it's also not the cheapest, but it does well to balance the cost and the functionality/reliability."
"The price of Quad9 is free."
