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

"The real reliability and uptime of the global Anycast service are 100%, which we really appreciate."

"We find that the low latency access to DNS queries has a direct effect on the customer experience. Visiting a site, whether it's an AdTech-based solution or marketing tech, the fact that whatever we're rendering on a page can be rendered better than the industry standard, in terms of time, ensures a better user experience."

"In general, I would say that this has been the easiest solution to manage and implement."

"Monitoring is really important for us. We really care about reliability, and we want to make sure that we can remove some points of presence in our sector and in our edge network really fast when we experience any problems. So, monitoring that NS1 provides for DNS is really important for us."

"Their Pulsar filters allow us to collect RUM metrics from our users so that we can determine the best paths for our users to take. That has been very useful in providing the best user experience, and for responding to and recovering from downtime of our multiple CDNs."

"The solution's stability is absolutely perfect."

"The Filter Chain is one of the most valuable features, for geo-load balancing and geo-fencing. The Filter Chain is the most useful because it allows us to do several things. With geo-fencing we can redirect a particular user to a particular answer. That's very valuable for us. Filter Chains with monitoring is our strategy to provide redundancy."

"Managed DNS helped improve our end-user experience, it reduced our latency dramatically, and our users' experience is much better now."

More IBM NS1 Connect pros

"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

"We would really like them to become a DNS registrar."

"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."

"I would love to see improvement in the testing capabilities they provide. They have a simulate-filter feature so that you can simulate how your traffic would flow, based on their Filter Chains. I believe that was shut off for quite some time. Having that as a way to test our load-balanced CDN structure would be fantastic."

"There could maybe be additional ways to manage traffic. There are no major improvements we're looking for. It's a very complete solution."

"IBM NS1 Connect has a very steep learning curve in terms of learning the custom filter chains and the complex multi-region setup, which requires a specialized DNS expert and can be difficult for beginners."

"I would love to see improvement in the testing capabilities they provide."

"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.""

"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."

More IBM NS1 Connect cons

"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."

"Quad9 could improve by having more free features, such as custom DNS filtering."

Pricing and Cost Advice

"The cost of this product is one of the reasons that we chose it."

"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."

"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."

"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."
