If DNS is the phone book of the Internet, DNSSEC is the Internet’s unspoofable caller ID. It guarantees a web application’s traffic is safely routed to the correct servers so that a site’s visitors are not intercepted by a hidden “man-in-the-middle” attacker. These attacks usually go unnoticed by sites’ visitors, increasing the risk of phishing, malware infections, and personal data leakage.

Cloudflare provides insight to your website traffic that you can’t get from other analytics programs.
In addition to visitor analytics, you can monitor threats and search engine crawlers. For most websites, these threats and crawlers make up 20% to 50% of traffic. It’s traffic every website should understand, but most analytics services ignore.
Argo Smart Routing reduces Internet latency on average by 35%; connection errors by 27%.
Content delivered from a customer server relies on the quality of established network paths for consistently fast performance. Traditional networking technologies utilize static routing information that can send content across slow and congested paths. Slow loading times and connection timeouts increase the likelihood of a poor user experience that can reduce revenue or damage brand reputation.
Cloudflare routes 10% of all HTTP/HTTPS Internet traffic providing Argo with real-time intelligence on the true speed of network paths. Argo's smart routing algorithm uses this information to route traffic across the fastest paths available, and maintains open, secure connections to eliminate latency imposed by connection setup. Argo’s tiered caching technology uses regional tier 1 Cloudflare data centers to propagate content to Cloudflare’s global network of 155+ Data Centers, minimizing requests to servers and reducing costs.
With almost half of online consumers saying they will abandon a page that takes more than 2 seconds to load, speed has emerged as one of the most straightforward ways to compete in the crowded, hypercompetitive online marketplace. Argo improves performance by routing visitors through the least congested and most reliable paths using Cloudflare's private network.
There’s a simpler and more secure way to protect your applications and web servers from direct attacks: Cloudflare’s Argo Tunnel. Learn more please click here.
Cloudflare’s global Anycast network ensures fast video delivery, with shorter video startup times and reduced buffering, no matter where your visitors are located.

Our rich ecosystem of performance and security services, tuned specifically for video, offer optimal uptime and delivery.
Visitors today expect fast, high-quality online video experiences, regardless of device, connection type, or location. Video services which fail to meet visitor expectations can experience lower engagement and revenues. Every incremental one-second buffering delay for video playback results in a six percent increase in abandonment rates.
Cloudflare’s global Anycast network ensures fast online video experiences, with shorter video startup times and reduced buffering, no matter where your visitors are located. Flat-rate bandwidth pricing ensures predictable costs, even in the case of legitimate traffic spikes or volumetric DDoS attack.
Cloudflare’s content delivery network (CDN) has 155 data centers across 75 countries, including 21 in China, ensuring the fastest delivery of high-quality video content at global scale. We ensure fast online video experiences, with shorter video startup times and reduced buffering. Video files can be selectively purged from Cloudflare’s entire network cache within seconds.
Railgun ensures that the connection between your origin server and the Cloudflare network is as fast as possible.
Railgun compresses previously uncacheable web objects up to 99.6% by leveraging techniques similar to those used in the compression of high-quality video. This results in an average 200% additional performance increase.
What Railgun Does
Railgun accelerates the connection between each Cloudflare data center and an origin server so that requests that cannot be served from the Cloudflare cache are nevertheless served very fast.
Approximately 2/3 of requests to sites on Cloudflare are served directly from cache from the data center that is physically closest to the person surfing the web. Because Cloudflare has data centers around the world this means that whether you are in Bangalore, Brisbane, Birmingham or Boston web pages are delivered quickly even when the real, origin web server is thousands of miles away.
Cloudflare’s ability to make a web site appear to be hosted close to web surfers is key in accelerating web surfing. A web site might be hosted in the US, but accessed mainly by web surfers in the UK. With Cloudflare the site will be served from a UK data center eliminating the costly delay caused by the speed of light.
But the other 1/3 of requests made to Cloudflare have to be sent to the origin server for processing. This happens because many web pages are not cacheable. This can be because of a misconfiguration, or, more commonly, because the web page changes frequently or is personalized.
For example, it’s hard to cache the New York Times home page for any length of time because the news changes and being up to date is essential to their business. And for a personalized web site like Facebook each user sees a different page even though the URL may be the same for different users.
Railgun uses a collection of techniques to accelerate and cache these previously uncacheable web pages so that even when the origin server must be consulted web pages are delivered quickly. And that even works for rapidly changing pages like news sites, or for personalized content.
Cloudflare research showed that even though many sites cannot be cached they actually change very slowly. For example, the New York Times home page changes throughout the day as news stories are written, but the boilerplate HTML of the page mostly stays the same and many stories stay on the front page all day.
For personalized sites the boilerplate HTML is the same with only small pieces of content (such as a person’s Twitter timeline or Facebook news feed) changing. This means there’s a huge opportunity to compress web pages for transmission if the unchanging parts of a page can be detected and only the differences transmitted.
How It Works
When a request is made to a Cloudflare server for a web page that is not in cache Cloudflare makes an HTTP connection to the origin server to request the page. It’s that HTTP connection that Railgun accelerates and secures.
Railgun consists of two software components: the Listener and Sender. The Railgun Listener is installed at your web host on an origin server. It’s a small piece of software that runs on a standard server and services requests from Cloudflare using the encrypted, binary Railgun protocol.
The Railgun Sender is installed in all Cloudflare data centers around the world and maintains connections with Railgun Listeners.
When an HTTP request comes in that must be handled by an origin server, Cloudflare determines whether it is destined for a Railgun-enabled website. If not, standard HTTP is used, but if so the HTTP request is routed to the Railgun Sender for handling.
The Railgun Sender turns the request into a compressed, binary chunk that’s transmitted to the corresponding Railgun Listener. The Railgun Listener handles the request and performs an HTTP request to the origin server. From the origin server’s perspective it’s as if the HTTP connection came directly from Cloudflare, but because it comes from inside the hosting partner’s infrastructure the request suffers no latency related delay.
Railgun uses a new caching mechanism based on comparing page versions to determine what needs to be transmitted across the Internet to the Railgun Sender. Using this mechanism Cloudflare is able to achieve typical 99.6% compression (taking, for example, a 100k web page down to 400 bytes) and a speedup of over 700%. In fact, the compressed data is often so small that using the binary Railgun protocol the entire response fits inside a single TCP packet.
Railgun connections are secured by TLS so that requests sent across them cannot be eavesdropped upon. The connection is secured by certificates so that a man-in-the-middle attack is not possible. The TCP connection between Cloudflare and the origin server is kept alive so that it can be reused for subsequent requests eliminating the slow start up of a TCP connection.
Railgun requests are multiplexed onto the same connection and can be handled asynchronously. This means that Railgun is able to handle many, simultaneous requests without blocking and maximizing the use of the TCP connection.
Over-utilized or geographically distant servers add unnecessary latency and degrade the visitor experience. In many cases, unreliable or misconfigured servers drop visitor requests completely, preventing access to websites, web apps or APIs. Poor visitor experiences like these have a direct impact on revenue, reputation, and customer loyalty.
Expanding on Cloudflare’s highly available DNS infrastructure and global Anycast network, Cloudflare Load Balancing addresses these issues by providing:
1. Local and global load balancing to reduce latency by load balancing traffic across multiple servers or by routing traffic to the closest geolocation region.
2. Health checks with fast failover to rapidly route visitors away from failures.
Rate Limiting protects against denial-of-service attacks, brute-force login attempts, and other types of abusive behavior targeting the application layer.
Cloudflare’s 20 Tbps global anycast network is 15x bigger than the largest DDoS attack ever recorded, allowing all internet assets on Cloudflare’s network to withstand even massive DDoS attacks.
Rate Limiting provides the ability to configure thresholds, define responses, and gain valuable insights into specific URLs of websites, applications, or API endpoints. It adds granular HTTP/HTTPS traffic control to complement Cloudflare’s DDoS protection and Web Application Firewall (WAF) solutions. Cloudflare charges based on “good” requests i.e requests that match a rule you have created and are allowed to origin servers. This also reduces bandwidth costs by eliminating unpredictable traffic spikes or attacks.
