Handles customer-facing records and upstream selection logic with good efficiency

We leverage two things from Managed DNS that we couldn't do with any other solution. One is their filter chain technology, which allows us to shift some of the intelligence we need for the traffic steering to the DNS. The second one is data sources, which enables us to manipulate multiple records simultaneously using NS1's internal message DOS. In our case, we are trying to direct the traffic in over 150,000 different NS1 records to an arbitrary set of repeating responses. If we have about 1,000 endpoints, that translates to around 150,000 records. Assuming there's an even distribution, so every time a server fails or an endpoint goes on a level, we would have 150 updates. With NS1, we have one, so this had an even more significant effect. There are situations where we have thousands of specific records sharing the same responses. In that case, there is one update instead of thousands and thousands. When we chose Managed DNS in 2014, it was the only solution that could do what we wanted, but I'm not sure about the current state of the market. The NS1 API is an API on top of a managed DNS. It's not an afterthought. It's not like the solution existed. Someone was sending updates by email. Then a product manager came along and said, "Hey, there is this cool thing. It's called an API. Maybe we should do it?" And they are like, "Okay. Let's do it." In the case of NS1, they thought about how to use an API to manipulate and retrieve the stuff. It's supposed to be API-driven. Also, NS1 doesn't have hidden features that would not be available over the API. Even their dashboard is built on top of the API. You can leverage all the functionality programmatically. That's what we do. We don't use their native integrations because we have been customers before these integrations and real-time telemetry existed. Our solution isn't leveraging either of those. Instead, we leveraged their API integration, which was the first thing that existed. Indeed, the API is at the core of how we use Managed DNS. No one goes to the dashboard or manually clicks anything. Everything goes via the API, and we perform hundreds of changes every minute. The API automatically drives everything, so that's the integration we leverage. We don't use the Pulsar Active Steering feature because we don't have a website. Our solution is being used as an API for other solutions. You can put the Pulsar agent on the website and feed NS1 the information. In our case, we are integrating into third-party sites. We cannot put our JavaScript on their websites for NS1 to provide the data, so we don't.

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

"We leverage two things from Managed DNS that we couldn't do with any other solution. One is their filter chain technology, which allows us to shift some of the intelligence we need for the traffic steering to the DNS. The second one is data sources, which enables us to manipulate multiple records simultaneously using NS1's internal message DOS. In our case, we are trying to direct the traffic in over 150,000 different NS1 records to an arbitrary set of repeating responses."

"It massively speeds things up. Today, we allow developers to deploy services and have externally facing DNS scrapers that are created automatically without the addition of human intervention."

"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."

"The fact that it's an API-first platform for DNS and application traffic management is one of the reasons we looked into NS1. We use it for a lot of automation and metrics gathering and it's been great."

"The provisioning is great. They have an API service that is simple to use and very quick. The changes that we make are replicated worldwide in a matter of usually milliseconds, sometimes seconds. They are done very rapidly. That's something that's obviously priceless when we're dealing with things like DNS."

"Everything we download into our observability platform so that we can also track any changes in traffic behavior or things like that is also something that we use quite a lot. I'd say traffic management, the speed of updates, and observability are the top three things that we use."

"One of the features that is non-standard and that is very useful is the filtered DNS. We have set up our external VPN, which is what all our employees connect through, to use this feature. It's geolocation-aware. In that way, for India we set it up so that these are the servers that should be supporting things, and in the UK these servers, in the U.S. these servers, and in Sweden these ones."

"For starters, it integrates with Terraform and a lot of our infrastructure is effectively built out using Terraform. That makes all this stuff extremely easy... when we deploy, all the entries are created and configuration is done."

More IBM NS1 Connect pros

"The most valuable feature of Quad9 is that it is a free solution."

"Setting up Quad9 is straightforward if you know what you're doing, and it's easy to use overall."

Cons

"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."

"We care about monitoring and telemetry work, and NS1 provides a pretty good system for monitoring. We can monitor our endpoints and points of presence around the world. If there are any issues, we can easily remove them from our network, but this area needs some improvement because it is not always reliable in NS1. In the past, we had a number of false-positive cases when the monitoring system told us about some problems in our infrastructure that were not true. NS1 is improving the system, and we are constantly talking about this with them. I know that they are releasing a new version of their monitoring system, which is really important for us, but this is a different area where we would expect them to improve."

"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."

"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 reporting metrics are great from an API standpoint, but it would be a little bit nicer if there was some type of dashboard around that. There should also be some type of reporting that's more executive-level focused."

"We use the geo load balancing functionality and there are a couple of things that are helpful there. But the language itself is something we had to get used to a little bit. Some of my folks made a few mistakes in rolling out the Filter Chain...The Filter Chain setup is a bit hard to grasp at first. It would also be nice to have a way to simulate changes in addition to staging."

"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."

More IBM NS1 Connect cons

"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

"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."

"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."

"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."

"The price of Quad9 is free."
