On February 20, 2025, at 16:22 UTC, StatusGator detected an outage affecting Vultr. The issue appeared to stem from a DNS failure, causing vultr.com and any other services hosted on its domain to become inaccessible. But what does that include? The official Vultr status page. Because Vultr hosts its status page on status.vultr.com, the same domain hosting its primary website and dashboard, users were left without an official source of updates during the outage.

You can think about a website the same way you think about your car. Every time something breaks, a professional—an engineer or a mechanic—usually charges a high amount for the fix (isn’t it annoying when you can’t tell if it’s a big or small fix?). Alternatively, you can learn some basics, get a few inexpensive tools, and troubleshoot many of the immediate issues yourself.

Recently we’ve explored the evolving role of Kubernetes as a full ecosystem, rather than just a platform, diving into the power and complexity of add-ons. These tools, as highlighted previously, are key to augmenting Kubernetes core capabilities, and adding-on (as their name implies) essential capabilities not supported directly by Kubernetes itself.

In January 2025, security researchers uncovered a critical DNS misconfiguration involving Mastercard. For nearly five years, one of Mastercard’s DNS records pointed to the incorrect domain "akam.ne" instead of the intended "akam.net." This error, caused by a simple typographical mistake, created a vulnerability that could have allowed malicious actors to intercept or redirect traffic.

A load balancer, also known as Global Server Load Balancing (GSLB), is the method of splitting and distributing the incoming network traffic to multiple hosts—which can be located at different geo locations—within the organization network. This helps the network effectively manage network traffic and prevent any delays in network services. With load balancing enabled in the hosts, the organization’s network services are faster and provide more reliable responses to clients.

A DNS zone transfer is the process of transferring DNS records and zone files data from the primary server to the secondary server. This updates the secondary server with the current records and zone files so that it can act as a backup during failover scenarios. Zone transfer extends network services when the primary server fails by copying the primary server’s files to the secondary server.

DNS monitoring ensures your domain records are accurate, secure, and performing well, helping prevent outages and attacks.

Both CNAME and ALIAS records share a common purpose: They map one or multiple domain names (such as those for different departments or regions) to a main target domain. However, their specific uses and functionality differ in various network scenarios. Network administrators need to understand these distinctions to leverage each record type effectively for robust network services. This blog will help you understand the differences between CNAME and ALIAS records and their applications.
