DNS Failover Explained: From Health Checks to Hands-Free Automation If your primary server, data center, or cloud region goes down at 3 a.m., how long does it take for traffic to move somewhere healthy, and who needs to be awake to make it happen? For many teams, the answer still involves a pager, a VPN […]
SOC 2 Type 2 and Operational Resilience: Why Independent Assurance Matters Every infrastructure provider can say its platform is secure, resilient, and ready for the enterprise. The harder question is whether the controls behind those claims have been independently examined and shown to work consistently over time. For organizations running payment systems, customer-facing applications, regulated […]
What Is Load Balancing, and Do I Need It? Most people never think about load balancing until something stops working. A website becomes painfully slow during a traffic spike. An application server fails and suddenly nobody can log in. A planned maintenance window turns into an outage because there is nowhere else to send users. […]
Why your DNS shouldn’t live inside your cloud provider On October 19 and 20, 2025, AWS ran into the kind of failure that is easy to assume only happens somewhere else. A latent race condition inside AWS’s own DNS automation wrote an empty DNS record for the DynamoDB endpoint in us-east-1. DynamoDB itself was healthy, […]
Free DNS vs. Managed DNS: The Real Cost of “Good Enough” If your DNS came bundled with your domain registration, or you pointed your nameservers at Cloudflare’s free plan years ago and haven’t thought much about it since, you’re certainly not alone. For many small and mid-sized businesses, DNS feels like a problem that has […]
The World’s Biggest DNS Outages: What Actually Caused Them and How to Avoid Being Next When a major online service suddenly disappears, the first assumption is often that someone is attacking it. Sometimes that is exactly what happened. The Dyn outage in 2016 is a good example. But look at the post-mortems from some […]
Why DNS is the most underestimated single point of failure in your infrastructure If you are responsible for infrastructure at a midsize enterprise, you have probably spent a considerable amount of time and money removing single points of failure. Workloads may be distributed across multiple data centers or availability zones. Databases are replicated. Network and […]
Your DNS may be in the same failure domain as your CDN or Cloud Provider You have redundant servers. Multiple availability zones. Health checks. A CDN. A WAF. Perhaps even a second cloud region ready to take traffic. But there is a question that is surprisingly easy to overlook: Who runs your DNS? If the answer is […]
Instant Disaster Recovery: Move Your Applications Without Changing a Single IP Disaster recovery has quietly become a compliance problem as much as a technical one. Under the EU’s Digital Operational Resilience Act (DORA), in force since January 2025, financial entities must demonstrate and test their ability to withstand and recover from ICT disruption, with business […]
The static IP that doesn’t break when your ISP does Ask any IT manager what happens when their primary internet provider goes down, and you’ll usually hear the same reassuring answer: “We have a second ISP.” It sounds like resilience. In practice, for anything that depends on a fixed IP address, it often isn’t resilience […]
