Suddenly Corriere della Sera, Gazzetta dello Sport, Twitch, Reddit, Amazon, Github, Guardian, The Verge, Financial Times, BBC, New York Times and many other sites of international importance fell and were unreachable for a few hours. The situation has been restored a few minutes ago and now there is also an explanation for the problem: the network Fastly.
Fastly: CDN has fallen
The fallen sites rested their resources (CSS, js, images or more) on the servers of the CDN Fastly, where performance problems have begun to be reported since mid-morning. In the following hours, the group reported ongoing investigations into the problem, in response to sure requests from the publishers involved. Just a few minutes ago the problem was indicated as solved by Fastly itself:
The problem has been identified and a fix has been applied.
Fastly has not yet explained the cause of the incident, limiting itself to notifying the restoration of the situation on the “Content Delivery Network“And full recovery of assets. Furthermore, the problem would not have involved a single datacenter, but would have spread over the entire global network of the group.
The fall of the CDN led in some cases to the unreachability of CSS (with sites that therefore appeared with skipped graphics and relative impossibility of navigation, as in the Github case) and in other cases to the complete unreachability of the site. CDNs, acting as a proxy and allowing you to improve the performance and speed of your pages, allow you to improve the user experience on the sites that host their resources on these servers. The fall of the entire network is therefore equivalent to the fall of essential parts of the sites involved, resulting in the different inefficiencies recorded in these hours.
