What is Cloudflare?

From time to time we have to give the news that the internet has collapsed. Panic begins to spread when users try to access a web page and it does not work, instead of the usual content the screen only shows a 502 and the message Bad Gateway.

From time to time we have to give the news that the internet has collapsed. Panic begins to spread when users try to access a web page and it does not work, instead of the usual content the screen only shows a 502 and the message Bad Gateway.

Why does this happen? Do you know what Cloudflare is and what it is?

There may be many reasons why the internet is not working properly, but what appears in the window of your browser is a 502, calm down you are not to blame. The only ones responsible for that fall are companies like which we are going to talk about today: Cloudflare

A 502 implies that the failure has occurred in companies called CDNs. But let’s start at the beginning: Internet works by connecting some computers with others, so if we want to access a web page that is on a specific server, only those closest to that server will have good access and high connection speed. .

For that, networks of servers were created all over the world that store and replicate the websites, applications and data that circulate through the network so that we all have them as close as possible and have a similar quality of access.

Its name is CDN and they have become a substantial part of the network and services such as streaming platforms or social networks that we want to access from any place and at any time, without suffering the so-called low latency.

In 2009 Cloudflare was founded with this concept, but during these years this company and similar ones have gone further. In addition to offering an optimal solution in the content distribution network, Cloudflare has proposed to protect us from cyber attacks.

Companies that hired Cloudflare servers to be on the Internet like Dropbox or Pinterest, for example, also had cybersecurity protection services against DDoS attacks.

The DNS 1.1.1.1 service that promises to respect the privacy of users and a Warp VPN are some of the tools that Cloudflare has created and with which it has created a more secure service that stood out above other CDNs.

By acting as intermediaries between the client and the server with the reverse proxies, they can detect malicious traffic and limit spam on the network. However, from time to time problems arise.

It is not very often, but the infrastructure can fail and that is when the famous 502 appears and the websites that depend on that CDNs do not work. Just a month ago we were witnesses and victims of one of these problems blocking millions of websites.

It is a problem that we cannot do other than wait for them to solve it. Be patient and check from time to time the social networks of these companies where they usually report these problems.
