Today’s Tip of the Day is the final of three focused on Domain Name System (DNS) monitoring. In the rest of the series, we looked at how digital experience monitoring (DEM) can (i) help ensure users are served by the correct DNS server to reduce latency and (ii) help to guard against DNS-related attacks. In today’s post, we talk about Anycast DNS, the advantages it provides, the challenges it presents in relation to troubleshooting DNS issues, and how to overcome them with Catchpoint.
Today’s Tip of the Day is the second in a three-part series on Domain Name System (DNS) monitoring. In the first, we looked at how the application delivery chain works and the way in which many companies outsource their DNS to third parties with a global presence in order to reduce latency. The connected tip was focused on ensuring users are served by the correct DNS server.
Keeping a server running optimally on a consistent basis involves managing multiple system elements simultaneously. Automated scripts and specialized software can handle the tasks your server needs to complete on a daily basis—but when one of these experiences an error, it can throw the entire system off.
Did you know that around 306 billion emails have been sent globally every day in 2020 and about 45 percent of all emails received are spam. Even more surprisingly, websites that are marked as spam on email portals lose 95 percent of their traffic. Email servers tend to blacklist certain IDs as spam based on their content. And for companies marketing their business via emails, 36 percent of the total spam messages across the globe are attributed to advertising content.
This Tip of the Day is the first in a three-part series on Domain Name System (DNS) monitoring. The Domain Name System is often described as “the phonebook of the Internet.” While humans access the Internet via domain names such as npr.org or bbc.com, web browsers interact via Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so that browsers know which Internet resources to load.
On Star Trek, there’s an incredibly useful device called the universal translator. As you’d expect, it allows everyone to understand each other. For example, if Captain Jean Luc Picard bumped into a race of aliens that bore a striking resemblance to Commander Riker’s beard, then they could set a date for some Earl Grey tea (hot) thanks to the universal translator. Without it, there might be grave misunderstandings and the firing of photon torpedoes.
