Why Your Domain Is Using Cloudflare (And When to Worry)

What Is Cloudflare

You just ran a TechSpy scan on your domain. Among the results, you see that your nameservers point to or a CNAME record leads to . Maybe you didn’t set this up. Maybe someone in IT did three years ago and forgot to mention it.

Cloudflare is a service that sits between the internet and your website, like a security checkpoint at a building’s entrance. When people visit your domain, Cloudflare’s network handles the request before it ever reaches your actual web server. It can speed up loading times, block malicious traffic, and hide your server’s real address.

Specifically, Cloudflare provides three main things:

When TechSpy notes Cloudflare, it usually means your domain’s nameservers are Cloudflare’s, or certain CNAME records point to Cloudflare’s proxy. This isn’t automatically bad, but it means Cloudflare is the middleman for your traffic and you should understand what it’s doing.

CDN (Content Delivery Network): A bunch of servers scattered around the world that keep copies of your site’s static files (images, CSS, JavaScript). So someone in Tokyo loads your page from a Tokyo data center, not from your one server in Chicago.

DDoS protection: If someone tries to flood your site with junk traffic to knock it offline, Cloudflare absorbs that flood so your server never feels it.

DNS management: You can manage all your domain’s records—where your website lives (A records), where your email goes (MX records), and security records like SPF—from Cloudflare’s dashboard.

Real-World Analogy

Think of Cloudflare like a valet service at a restaurant. Guests drive up, hand their car to the valet, and the valet parks it somewhere hidden. When they’re ready to leave, the valet retrieves the car—fast, safe, and the guests never see the parking garage. Cloudflare does the same: it takes visitor requests, handles them securely (sometimes from a nearby cached copy), and shields your real server from public view.

How Cloudflare Works

Plain-English Version

When someone types your domain name into their browser, their computer first asks “Where is this site?” That question gets answered by DNS—the internet’s phone book. If your domain uses Cloudflare’s nameservers, the answer comes from Cloudflare’s global DNS network, which is very fast and hard to overwhelm.

Once the browser knows where to go, the request hits a Cloudflare data center close to the user. If the visitor is loading your homepage, Cloudflare might already have a cached copy of the images and code stored right there. It can deliver that instantly without ever bothering your hosting server. If the request is part of a coordinated attack—thousands of computers trying to overload your site—Cloudflare detects the pattern and blocks it, soaking up the traffic before your server even notices.

For email, things work differently. Email delivery does not go through Cloudflare’s proxy unless someone mistakenly turned on “proxy” for your MX records. If your MX records show the gray cloud (DNS only) in Cloudflare’s dashboard, email flows normally. The TechSpy scan might flag Cloudflare simply because the nameservers are Cloudflare’s, not because email is broken. But it’s a reminder to check that those records aren’t set to the orange-cloud proxy setting.

Technical Details

▸Nameservers: Delegated nameservers like , , etc., mean Cloudflare’s DNS platform controls all DNS records for the domain.

▸CNAME records: A record like routes that subdomain through Cloudflare’s reverse proxy, hiding the origin IP.

▸Reverse proxy: Cloudflare terminates the visitor's TLS (SSL) connection at its edge, inspects traffic, then creates a new encrypted session to your origin server. The world sees Cloudflare’s IP, not yours.

▸DDoS protection: Cloudflare’s network analyzes traffic and drops malicious packets before they reach your server, using heuristics and known attack signatures.

▸Email: MX, SPF, DKIM, DMARC, and other email-related records must be set to “DNS only” (gray cloud). If they are proxied (orange cloud), email delivery will fail because Cloudflare cannot route SMTP traffic through its reverse proxy.

Why It Matters for Your Business

When Cloudflare is set up correctly, your site loads noticeably faster for visitors anywhere in the world. That means lower bounce rates, better SEO rankings, and happier customers. It also protects your domain from being knocked offline by a DDoS attack—something that could cost you sales every minute your site is down.

If Cloudflare is misconfigured, the impact can be sneaky and disruptive. The most common email-breaking mistake is having your MX records set to proxied. Suddenly, invoices don’t go out, support tickets vanish, and nobody can reach you. Even if email seems fine, a TechSpy warning about Cloudflare can point to DNS settings that are just a checkbox away from causing trouble.

This isn’t just an IT concern. Your marketing team cares about page load speed because it affects conversion rates. Your sales team cares about uptime when a big prospect tries to visit. Your support team needs email to work. If your domain’s DNS is managed through Cloudflare—intentionally or not—you should know who set it up and why.

Common Issues and Warning Signs

A Cloudflare setup that’s drifted from best practices often shows itself in subtle ways before something big breaks. Here are the signs to look for, based on what TechSpy checks and what real users report.

Common Issues

Emails start bouncing or going to spam, and your MX record in Cloudflare’s dashboard shows an orange cloud (proxied). That means email traffic is hitting Cloudflare’s proxy, which isn’t built to handle SMTP, and messages get lost.

Your website loads, but some subdomains (like or ) won’t connect. The A record for those subdomains might be set to proxied, but your origin server isn’t configured to accept connections from Cloudflare’s IP ranges.

Visitors see SSL certificate errors. This can happen if Cloudflare’s universal SSL is expired or the encryption mode is set too loosely, and the origin server’s certificate doesn’t match.

TechSpy reports that your domain uses Cloudflare nameservers, but nobody on your team authorized the change. This could mean a former employee or agency still controls the DNS, or worse, your domain’s nameservers were hijacked.

Your site is slow even though Cloudflare is active. This often means caching isn’t enabled properly, or a critical DNS record is pointing to a wrong IP, and Cloudflare is passing through traffic without optimizing it.

How to Fix or Improve Your Cloudflare Configuration

The path forward depends on whether you actually need Cloudflare. If you run a public website and want the speed and security benefits, you’ll want to fix any misconfigurations. If you never intended to use Cloudflare, you can remove it. Either way, start by identifying who set it up—that might be your current IT team, a former developer, or your hosting provider.

After any changes, run another TechSpy scan. It takes less than a minute and will tell you immediately if the Cloudflare flag is resolved—and whether your email security records are finally in order.

If you want to keep Cloudflare but clean up the configuration:

1Log into your Cloudflare account. If you don’t have credentials, ask whoever set it up or use the account recovery process.

2Go to the DNS settings for your domain.

3For every record related to email—MX, SPF (TXT), DKIM (TXT with ), DMARC (), and autodiscover—make sure the proxy status is the gray cloud (labeled “DNS only”). If you see an orange cloud next to any of these, click it to turn it gray.

4For website records (A records for root domain, CNAME for ), the orange cloud is fine, but verify that your origin hosting accepts traffic from Cloudflare’s IP ranges (most modern hosts do; if you’re unsure, check with your host).

5In the SSL/TLS tab, set encryption mode to “Full” or “Full (strict)” if your origin server has a valid certificate. Avoid “Flexible” unless you fully understand the security trade-off.

6Run a TechSpy scan again to confirm the warning has cleared.

If you don’t need Cloudflare and want to remove it:

1First, back up all your current DNS records from Cloudflare’s dashboard (export as a CSV or screenshot each record). You’ll need to re-enter them elsewhere.

2Choose a new DNS provider—often your domain registrar or web host offers free DNS management.

3At your new provider, create all the records you backed up, exactly as they were except for any Cloudflare-specific CNAME entries.

4At your domain registrar, change the nameservers to those provided by your new DNS host (e.g., , ).

5Wait up to 48 hours for the change to propagate globally, then run a TechSpy scan to confirm Cloudflare is no longer involved.

If you’re not comfortable making these changes, forward this article and your TechSpy scan results to whoever manages your IT. They’ll have a clear checklist to follow.
