Comparing the performance of popular public DNS providers

ThousandEyes, a network intelligence company with the ability to monitor performance from hundreds of vantage points across the Internet, has insight into a variety of services across the globe, including public DNS service providers.  In this article we’ll dive into our results from testing 10 of the most popular public DNS resolvers, with the goal of helping you make informed conclusions about your choice of provider. We observed a wide range of performance across different services, both globally and from region to region.The Domain Name System (DNS) is the internet’s system for converting alphabetic web addresses into numeric IP addresses. If a given service’s DNS records are unavailable, the service is effectively down and inaccessible to everyone.  DNS can also have a substantial impact on page load time and web page performance. While it’s just the first step of many in the page load process (see the below image), any increase in DNS lookup time will directly increase load times. DNS lookup time, in turn, is directly affected by latency to the DNS server.To read this article in full or to leave a comment, please click here

Tips for building SD-WANs

The substantially high cost of MPLS circuits ($200-$400/Mbps/month) compared to easily deployed, lower cost broadband Internet (with a price tag of $1/Mbps/month) has triggered a shift in enterprise architectures to the software defined WAN. SD-WAN provides the flexibility to choose the most optimal transport and dynamically steer traffic over a mix of MPLS circuits, the public Internet, or even wireless LTE circuits.  The access transport selection depends on a variety of factors, including the type of application, traffic profile, security requirements, QoS and network loss and latency. When implemented correctly, SD-WAN truly has significant advantages: Faster service deployment, increased flexibility, unified management and improved application performance, to name a few. But, while familiarity about SD-WAN has increased over the last year, a survey by Silver Peak and IDG shows only 27% of small- to mid-sized enterprises have shifted to SD-WAN.To read this article in full or to leave a comment, please click here
