How to Fix DNS Problems
All the problems that could go wrong with DNS and why "It's always a Freaking DNS Issue" according to DevOps movement co-founder and open source advocate Kris Buytaert.

Domain Health Check: Why It Matters and What It Reveals
Your domain is more than a URL- it’s the control plane for how people (and machines) reach your website, apps, and inbox. When something breaks at the domain layer, the symptoms look “random” (site intermittently down, emails bouncing, logins failing), but the root cause is often predictable: misconfigurations, weak authentication, or degraded DNS performance. A domain health check is the fastest way to surface those issues before customers do.
Best DNS Monitoring Tools in 2026
DNS monitoring is the practice of continuously checking that your domain names resolve correctly (right records, right answers) and that DNS lookups are fast and reliable from multiple locations. Depending on the tool, it can also watch for unexpected DNS record changes (A/AAAA/CNAME/MX/NS/TXT, etc.), validate DNSSEC, and pinpoint where resolution breaks in the chain.
Delegated DNS validation: proving domain ownership without exposing credentials
It seems like every service wants proof you control your domain. Certificate authorities need it to issue certificates. Email platforms need it to authorize sending. Analytics needs it to gather data. Just add this magic TXT record to your DNS, wait for propagation, click verify. It works fine when it’s a one-time setup, but certificate lifetimes are dropping to 47 days, and you won’t be able to keep up on that schedule.
Multi-environment DNS automation on Cloudflare using CircleCI and Terraform
Manually configuring DNS records for staging and production environments is a common pain point for developers and DevOps teams. As your organization grows and you manage more applications across different services, keeping DNS records up-to-date and error-free becomes increasingly challenging and time-consuming. Mistakes in DNS setup can lead to downtime, broken environments, or confusing deployments, especially when juggling multiple teams or microservices.
Guided DNS Troubleshooting, Full History, and UI Improvements
We're kicking off 2026 by shipping improvements that make DNS troubleshooting faster and more intuitive. When a DNS check fails, you'll now see exactly what needs to change to fix it, and you'll have complete visibility into your DNS record behavior over time.
The Domain Management Framework Ops Teams Should Be Using in 2026
You've probably had that moment. A minor outage hits production, and after a few hours of head-scratching, someone traces it back to a domain issue. Expired records, a DNS change that didn't propagate, a forgotten subdomain pointing to nothing. It always seems small-until it's not. And in most Ops teams, domains are still treated like static assets when they're anything but.

Cascading Failures Aren't Inevitable: Lessons from the AWS DNS Outage
AWS outages grab headlines because they affect millions, but the root cause often comes down to something invisible: DNS failures and cascading service dependencies. The complexity of modern cloud systems, combined with the advanced technology powering platforms like AWS, makes these outages particularly challenging to diagnose and resolve. The recent AWS outage proves one thing: you can't prevent every DNS issue, but you can create resilient architectures and prevent a single failure from taking down your entire service if you test for it.
Detect DNS Record Creation: Planned or Rogue
We're excited to announce one of our most frequently requested features: inverted DNS checks. This new capability allows you to detect when DNS records are created (whether they're planned infrastructure changes or rogue records) and prevent unwanted values from appearing in your DNS configuration.
DNS Outages Expose Hidden Risks. Edwin AI Finds Them Faster.
The recent AWS outage exposed how fragile the internet remains. Amazon traced the hours-long disruption to a DNS error—a small failure with massive reach. For most organizations, DNS operates quietly in the background. When it fails, every digital service connected to it stops. One of LogicMonitor’s valued customers, IG Group, faced a similar event less than ten hours after enabling Edwin AI.
