Its Always DNS
DNS Outages Are a Business Redundancy Wake-Up Call
Recent internet disruptions caused by DNS failures have highlighted something every organization needs to take seriously: even the biggest players in the world can go down without warning. For businesses that rely on cloud tools, communications platforms, remote operations or online services, DNS outages are not just an IT problem. They are a business continuity risk.
Recent DNS Related Outages Show the Risks
- In October 2025, Amazon Web Services experienced a DNS related issue that disrupted major services in its US-EAST-1 region. Businesses that depended on AWS suddenly found key systems unreachable.
- In July 2025, Cloudflare’s 1.1.1.1 DNS resolver went offline worldwide for almost an hour, preventing millions of users from accessing websites and cloud applications.
- In November 2025, another DNS related event affected thousands of sites, again proving that a single DNS system failure can ripple across the entire internet.
These were not small companies with outdated infrastructure. These are some of the largest, most advanced providers in the world. If they can suffer DNS failures, any business can be impacted.
Why DNS Issues Threaten Business Redundancy
DNS is a critical layer of redundancy that many organizations forget to plan for. When DNS fails:
- Redundant servers do not matter if users cannot reach them
- Cloud failover does not activate because DNS cannot direct traffic
- Communication systems and customer portals become unreachable
- Revenue producing systems stop functioning
- Employees cannot access essential tools or data
A single weak point in DNS can quietly undermine every other redundancy strategy a business has invested in.
