Lessons from Cloudflare’s Outage

Yesterday’s global Cloudflare outage was a sharp reminder of a truth most engineers already know but rarely act on:

The internet is only as resilient as the weakest link in your stack — and sometimes that weakest link is a single, centralized provider.

When Cloudflare’s edge network struggled, users across the world were suddenly stuck behind broken bot checks, stalled CDN routes, and websites that simply wouldn’t load.
Even businesses that had rock-solid infrastructure behind the scenes still went down, because Cloudflare sat directly in front of everything — DNS, CDN, WAF, and traffic proxying.

It was a classic case of “Move to the cloud; it will be more reliable,” coming back to bite.

Avoiding Single Points of Failure in Your Infrastructure

Yesterday’s outage highlighted a fundamental architectural challenge:
Too many platforms rely on a single provider for critical layers of their stack.

When DNS, CDN, WAF, proxying, and edge logic are all controlled by one vendor, a failure in any one part can cascade and take your entire platform offline. This isn’t a Cloudflare problem — it’s a design problem that many businesses unknowingly create.

To avoid repeating yesterday’s disruption, we need to rethink how we architect resilience into our systems. And the solution doesn’t require abandoning Cloudflare — it requires avoiding single points of failure by using each provider for what they’re best at.


1. Separate DNS From Edge Proxying

The first and most important rule:

Your DNS should never depend on the same provider that handles your traffic proxying.

Why?
Because even if your origin is healthy, your DNS can become unreachable during a provider outage — and your entire domain will appear offline.

The fix:

  • Use AWS Route 53 as your authoritative DNS

  • Use Cloudflare strictly as your CDN, WAF, and reverse proxy

This gives you:

  • DNS independence

  • Control during outages

  • The ability to reroute traffic instantly

  • No dependency on Cloudflare’s DNS layer


2. Keep a Path to Bypass Cloudflare When Needed

If Cloudflare experiences issues, you should have the freedom to route traffic directly to your origin or to another CDN. With Route 53 handling DNS:

  • You can turn Cloudflare’s proxy off (grey-cloud)

  • You can swap A/AAAA records directly to your backend

  • You can switch the CDN to CloudFront, Fastly, or Akamai on demand

This keeps your business online while Cloudflare resolves the outage.


3. Don’t Put All Your Performance Logic in One Edge Network

Workers, firewall rules, caching, bot management — these features are powerful, but they can also create tight coupling.

A safer approach:

  • Keep core routing logic provider-agnostic

  • Use Cloudflare Workers for enhancements, not critical path logic

  • Mirror critical behavior in your application or in alternate CDNs where possible

This ensures your application doesn’t break when an edge provider has problems.


4. Implement Multi-CDN (Optional but powerful)

For high-traffic or mission-critical systems, a Multi-CDN strategy can eliminate regional or global dependencies:

  • Cloudflare for caching + security

  • CloudFront or Fastly as a fallback

  • Route 53 latency or health-based routing to shift traffic

This setup ensures:

  • No single CDN outage can take down your platform

  • Traffic can shift dynamically based on real-time conditions


5. Use Health Checks and Automation for Self-Healing

Combine Route 53 health checks with Cloudflare or secondary CDN failover rules to automatically reroute traffic when:

  • Your origin goes down

  • A CDN region becomes slow

  • A provider experiences an outage

Automation allows your system to recover without waiting for manual intervention.


6. Regularly Test Your Failover Plan

A failover plan that hasn’t been tested in production-like conditions isn’t a failover plan — it’s a hope.
Run periodic tests:

  • Can you bypass Cloudflare quickly?

  • Can your DNS swap to an alternate CDN?

  • Are your cache-control rules compatible across providers?

  • Will your application behave correctly without Cloudflare in front?

These tests are the difference between a 2-minute outage and a 2-hour outage.


A More Resilient Cloud Strategy

Yesterday’s Cloudflare incident wasn’t a condemnation of Cloudflare — it was a reminder of how deeply integrated these global networks have become into the modern internet.

The takeaway is simple:

Use Cloudflare for what it excels at — speed, security, and edge capabilities — but anchor your domain on a stable, independent DNS provider and maintain the ability to route around failures.

Architecting for resilience doesn’t mean buying more services — it means designing carefully so no single vendor outage can take everything offline.

By separating responsibilities, adding optional Multi-CDN redundancy, and keeping DNS independent, you can build an infrastructure that stays online even when large parts of the internet don’t.
