Category: DNS Disaster Recovery

Ensuring DNS resilience for remote branch offices presents unique challenges that differ from those faced by central corporate data centers. These branch locations often rely on centralized IT infrastructure for connectivity, yet they must also maintain local network functionality in case of outages. DNS is at the core of how branch offices communicate with corporate…

DNS logging and retention have become critical components of cybersecurity, compliance, and disaster recovery strategies, with regulatory requirements varying based on industry, region, and the nature of the data being handled. Organizations that fail to comply with DNS logging mandates risk legal penalties, data breaches, and operational disruptions. DNS logs provide valuable forensic data that…

When a DNS disaster occurs, the immediate priority is restoring service as quickly as possible. However, once the incident has been mitigated and normal operations have resumed, a thorough post-mortem analysis is necessary to understand what went wrong, why it happened, and how similar failures can be prevented in the future. DNS is the foundation…

A DNS failure can be one of the most disruptive events for an organization, impacting website accessibility, email delivery, cloud services, and internal business applications. When a DNS outage occurs, rapid coordination between IT, network engineering, security, and executive teams is critical to minimizing downtime and restoring services efficiently. A well-structured DNS disaster recovery war…

A DNS outage can have far-reaching consequences for businesses, affecting everything from customer access to mission-critical internal applications. Because DNS serves as the foundation for internet connectivity, any failure in resolution can lead to widespread service disruptions, financial losses, and reputational damage. Conducting a Business Impact Analysis (BIA) for DNS outages allows organizations to systematically…

DNS over HTTPS (DoH) and DNS over TLS (DoT) have emerged as critical protocols for enhancing the security and privacy of DNS traffic. Traditional DNS queries are sent in plaintext, making them susceptible to interception, manipulation, and exploitation by malicious actors. By encrypting DNS queries, DoH and DoT prevent eavesdropping and unauthorized modifications, ensuring that…

DNS disaster recovery requirements vary significantly across industries, as each sector has unique operational dependencies, regulatory obligations, and security concerns. While all organizations rely on DNS for business continuity, the level of risk and the specific measures required for DNS resilience depend on the industry’s reliance on real-time connectivity, customer-facing digital services, and internal network…

Managing DNS configurations manually is a complex and error-prone process, particularly in large-scale environments where multiple teams, applications, and infrastructure components rely on seamless name resolution. DNS misconfigurations can lead to outages, security vulnerabilities, and inconsistencies that disrupt operations and increase the risk of failures during disaster recovery scenarios. DNS Policy as Code offers a…

The growing complexity of IT environments has made traditional DNS disaster recovery strategies increasingly difficult to manage. As organizations scale their networks across multi-cloud infrastructures, hybrid data centers, and distributed edge environments, DNS failures have become more disruptive and harder to predict. Machine learning and AI-driven infrastructure are now playing a critical role in improving…

DNS is a critical component of modern internet and enterprise infrastructure, responsible for ensuring seamless domain resolution and maintaining connectivity across applications, cloud services, and internal networks. DNS failures can lead to widespread outages, performance degradation, and security vulnerabilities, making capacity planning an essential aspect of disaster recovery strategy. Without proper planning, DNS servers can…
