What does this mean and what are CDNs?
CDNs (Content Distribution Networks) are a fundamental part of the Internet infrastructure. Businesses around the world rely on server banks to improve Internet performance and access to online services. One way to do this is with CDNs, which cache data closer to the user to make the web pages easier to use. Especially the heavier ones, and with more elements like news websites.
As the problem did not come from servers but from these CDNs, depending on the connection of each user, some could access without problems while others received the famous 503 error.
The idea of content delivery networks (CDNs) is to eliminate potential data bottlenecks in the supply of the Internet, and their use has grown steadily around the world to help provide access to live streaming services and the Internet. letter, applications and social media platforms.
The result of a flaw in Fastly, which describes itself as an “edge cloud platform,” is that Internet users have been unable to access content and services depending on the proximity of the CDN they use.
Fastly is heavily used by data-intensive media outlets, which is why news sites, in particular, were negatively affected by the outage. The drop in Amazon’s online sales operations was also reported.
Deliveroo, Pinterest and Shazam are also prominent customers of the provider.
