**Crash breakdown analysis from Cloudflare**

**Cloudflare** is one of the world’s largest [**CDN services**](https://vncdn.vn/), helping businesses manage the server-to-client traffic quickly, thereby optimizing the site’s performance.

However, on July 2, the homepage and services of **Cloudflare** crashed, causing related websites to appear **502 Bad Gateway** error, affecting the operation of many users and businesses. while trying to access.

**Cloudflare** said the cause of the problem was a routing leak, causing many of the major websites to fail and shut down, including affected names like **Discord, Feedly, Crunchyroll. and Amazon.** Cloudflare acknowledges that this situation occurs worldwide and has taken quick remedies as soon as the incident occurred.

_The Cloudflare issue affects the activities of many users and businesses_

Through investigation, we can all see that the problem that **Cloudflare** encountered stemmed from a type of attack “deploying faulty software”. However, all services returned to normal operation after the **Cloudflare** issue was restored.

**Looking back from the previous AWS problem**

Back in 2017, **AWS** also had a similar problem with **Cloudflare**. As you know, most websites and web applications host their services on **AWS**. However, **AWS S3** encountered a problem that resulted in an offline state lasting 4 hours. This problem has caused many users to panic and worry because their daily trading activities and work are unexpectedly interrupted.

_This problem has happened with AWS before_

This problem is once again ongoing in the present with **Cloudflare**. In fact, when choosing a cloud computing solution provider, most of us often forget the importance of backup resources. Not because it doesn’t matter, but because of our subjective thinking that big [**CDN**](https://vncdn.vn/) suppliers will never have a problem. And therefore, businesses that do not have a backup solution will easily face unpredictable consequences when problems occur.

It seems that we have not learned any lessons from the **AWS** incident story.

**Linking various cloud storage services**

“Multi-Cloud” (or Cloud Link) has gradually become a common term and has been widely used in recent years, but it is not really a hot topic that has attracted a lot of interest in branch. However, when it comes to managing resource failure, Multi-Cloud is one of the best solutions available today.

This is an idea of combining multiple public infrastructures in the form of an Infrastructure that acts as a service (IaaS - Infrastructure as a service), such as **Microsoft Azure, Amazon Web Services or Google Cloud**. All of them act as part of a heterogeneous architecture (also known as Polynimbus cloud computing strategy). With this model, you are no longer dependent on a single cloud computing system to maintain operations, thereby helping to disperse risks and minimize downtime of the website.

**VNETWORK** has built, developed and perfected [**Multi CDN**](https://vnis.vn/noi-bat/multi-cdn) technology for many years. **Multi CDN** project is a combination of many **CDNs** on the same management platform. We have also built this platform with an AI (Artificial Intelligence) system that can help our users automatically switch to the **best CDN** for their website, avoiding the possibility of disconnection or disconnection.

Our platform helps ensure the safety and continuity of the website, avoiding incidents such as cable cuts, leading to internet outages. The **Multi CDN** solution also includes addressing serious problems of **Cloudflare** that occurred on July 2, 2019.
