Cloudflare Argo Smart Routing: What It Is and How to Configure It

You can optimize your server to perfection, but you cannot control the public internet. Data traveling long distances often hits congestion and inefficient routes, creating bottlenecks you can’t fix with code. This is why a high-performance site in New York often feels sluggish to a user in Tokyo.

Cloudflare Argo Smart Routing fixes this by bypassing the public internet’s volatility. It intelligently routes traffic through Cloudflare’s private network, ensuring the fastest path from your server to the user rather than the default one.

In this guide, we will break down how Argo works compared to standard routing and the real-world performance gains you can expect. We will also walk through how to enable Argo, specifically contrasting the expensive pay-as-you-go model with the flat-rate Enterprise method available on Cloudways.

What is Cloudflare Argo Smart Routing and How It Works?

To understand why Argo works well, look at how the standard internet operates. When someone requests your website, their data doesn’t go straight to your server. It travels across different networks managed by different ISPs, hopping from router to router until it gets there. BGP (Border Gateway Protocol) controls this journey.

Smart Routing vs. Standard BGP

Standard BGP is reliable but not “smart.” It finds the shortest physical path between two points based on network hops. It doesn’t check if that path is actually performing well.

If the shortest route between a user in London and your server in New York has 40% packet loss from a hardware failure or congestion, BGP sends traffic that way anyway. This causes high latency and connection timeouts.

Argo Smart Routing works differently. It ignores the default BGP route and uses Cloudflare’s global network to check real-time data on every available path. It looks at latency, packet loss, and congestion.

Argo picks the fastest path at that moment, not the shortest one. If the direct path is congested, Argo routes traffic through a cleaner alternative within Cloudflare’s private network, avoiding internet traffic jams.

Argo Tiered Caching

Smart Routing optimizes the path. Tiered Caching optimizes delivery.

In standard CDN setups, when a user in Singapore requests a file not cached on the Singapore edge server, that server fetches it from your origin server in the US. This takes time and creates latency.

Argo Tiered Caching adds a hierarchy. Cloudflare splits its data centers into lower and upper tiers:

1. Lower Tier (Edge): The data center closest to the user, like Singapore.
2. Upper Tier: A regional hub with a large cache, like a major Asian data center.

With Argo, if Singapore misses a cache, it checks the Upper Tier hub first instead of your origin. Upper tiers handle more traffic and are more likely to have cached content already.

This means cache hits come from a fast regional hub instead of your origin server. It cuts load on your hosting and speeds up delivery.

Key Performance Benefits of Argo Smart Routing

Turning on Argo does more than speed things up a bit. It solves real problems with how data travels across the internet. Optimize your data path and you get two major improvements:

1. Lower latency
2. Better connection stability

Latency and TTFB Reduction

Time to First Byte (TTFB) measures the gap between when your browser asks for something and when it gets the first piece of data back. Standard BGP routing makes TTFB jump high for international visitors because their data bounces through networks that aren’t built for speed.

Argo Smart Routing goes after these bottlenecks directly. Traffic moves through Cloudflare’s private backbone instead of the regular internet, creating a fast lane for your data. This helps most when visitors are far from your server and the normal internet route gets jammed up.

Impact:

• Global Traffic: Sites with visitors spread across different countries usually see latency drop 20% to 30%.
• Dynamic Content: Pages that can’t be cached, like eCommerce checkouts or member dashboards, get the biggest boost. Every request has to go back to your server for fresh data. Argo makes sure those requests take the quickest route available, keeping your site responsive no matter where people are browsing from.

Improved Connection Reliability

Speed means nothing when connections keep failing. The public internet drops packets all the time. Hardware breaks, cables get severed, routers get overloaded. Users see 522 Connection Timed Out errors and leave frustrated. Search engines pick up on these failures too.

Argo catches packet loss as it happens. Cloudflare tracks network health across their entire system in real-time. When Argo spots a bad route with heavy packet loss or jitter, it reroutes your traffic to a cleaner path right away.

This works like a self-healing system. For example:

• A major undersea cable gets cut?
• A regional internet provider goes down?

Argo sends traffic around the problem. Your users stay connected while everyone else sits there watching timeout errors.

How to Enable Argo Smart Routing (Cloudflare Direct)

Enabling Argo Smart Routing is a straightforward process within the Cloudflare dashboard. For this walkthrough, we will demonstrate the steps using the standard Free Tier interface to show you exactly where these settings are located and how to activate them.

Step 1: Log in and Select Your Domain

• Log into your Cloudflare dashboard.

• If you have multiple sites, click on the specific domain you want to speed up.

Step 2: Navigate to the Traffic Tab

On the left-hand sidebar, look for the Traffic icon. Click that, and then select Argo Smart Routing from the sub-menu.

Step 3: Toggle Argo On

You will see a main section labeled Argo Smart Routing that lists the potential performance gains (decreased load times and increased reliability). On the right side of this panel, click the blue Activate Argo button.

Step 4: Confirm the Pricing

After clicking activate, a popup window titled “Enable Argo on your account” will appear. This is Cloudflare’s mandatory disclaimer reminding you that Argo is a usage-based product. It clearly lists the fees: $5.00/month per website plus $0.10 per Gigabyte of transfer. Click Continue to proceed.

Step 5: Enter Payment Details

If you are on the free tier and haven’t set up billing yet, you will be taken to a payment screen. Because Argo incurs variable charges, you must have a valid credit card or PayPal account on file to cover the potential bandwidth costs.

Important Warning: The Cost of Usage

The screens you just clicked through highlight the main risk of using Argo directly. The $0.10 per GB fee means your costs scale linearly with your traffic.

If your website traffic takes off and pushes just 1 Terabyte (TB) of data, your bill for Argo alone jumps to over $100/month.

This unmetered pricing is why many high-traffic sites avoid direct implementation. Fortunately, you can access the exact same technology without the usage fees by using the Cloudways Cloudflare Enterprise Add-on, which offers a flat-rate alternative we will cover next.

Enabling Argo via Cloudways Cloudflare Enterprise Add-on

If the variable pricing of the direct method makes you nervous, we have a solution. We have integrated Cloudflare Enterprise directly into the Cloudways platform, which simplifies both the setup process and the billing model.

The key difference here is that Argo Smart Routing and Tiered Caching are enabled by default. You do not need to toggle them on manually or monitor your bandwidth usage to avoid surprise fees.

Integration and Activation

Instead of managing this inside the Cloudflare dashboard, you handle everything directly from your Cloudways application settings. We have streamlined the process so you can activate the Enterprise integration with just a few clicks.

For a complete, step-by-step walkthrough on how to configure the add-on and verify your domain, please refer to our guide on setting up the Cloudflare Enterprise CDN.

Managing DNS Updates

Once the add-on is enabled, you will need to update your DNS records to point to the Cloudflare network. You can do this through your current registrar (like Namecheap, GoDaddy, or Cloudflare DNS).

Alternatively, if you are using our DNS Made Easy add-on for high-performance management, you can update your records directly within the Cloudways platform.

Once the DNS propagates, Argo Smart Routing and Tiered Caching are active immediately.

There is no “switch” to flip. Our Enterprise network automatically routes your traffic through Cloudflare’s accelerated paths. You can learn more about how DNS propagation works in our detailed guide.

The Flat-Rate Pricing Advantage

The most significant difference isn’t just speed, it is cost predictability.

As we calculated earlier, enabling Argo directly on a busy site can result in a bill exceeding $100/month due to the variable $0.10/GB bandwidth fee.

Our Enterprise Add-on changes this to a flat rate of $4.99 per month (per domain). This fee covers the Enterprise license, Argo Smart Routing, Tiered Caching, and your first 100GB of Enterprise CDN bandwidth. If you exceed 100GB, the overage is charged at just $0.02 per GB—significantly lower than the $0.10 per GB direct rate.

Cost Comparison for 1TB of Transfer:

• Direct Cloudflare (Free Tier + Argo): ~$105/month
• Cloudways Enterprise Add-on: ~$5/month

For high-traffic sites, this structure allows you to utilize premium routing without the risk of uncapped usage fees scaling with your traffic.

Cloudflare Direct vs. Cloudways Enterprise

To help you decide which implementation fits your needs, here is a direct comparison of the feature set and cost structure between the standard free tier and the Cloudways Enterprise integration.

Wrapping Up!

Cloudflare Argo Smart Routing gives you real performance gains by actively managing your traffic path instead of leaving it to the open web’s defaults.

In this guide, we covered how Argo’s setup cuts latency and stops connection timeouts by using real-time network intelligence.

We also looked at two ways to implement this. For smaller projects, the direct pay-as-you-go model lets you test these benefits without commitment.

For high-traffic or business-critical sites where you need predictable costs, the Cloudways Cloudflare Enterprise Add-on works better. It gives you the same premium routing and tiered caching at a flat rate, so your performance scales without your bill exploding.
