Cloudflare outage

Cloudflare has apologized for an outage on Tuesday morning, tracing the problem to a configuration change during network upgrades.

Cloudflare is one of today's major content delivery networks (CDNs). The US firm also provides distributed denial-of-service protection to online domains, speed optimization, and various cybersecurity services.

On Tuesday morning, a number of websites and online services suddenly went down, including Feedly, Cloudflare itself, blogs, cryptocurrency services, and more. Ironically

this also meant that down detectors -- websites used to check the status of another domain you are having trouble connecting to -- also went offline.

The outage caused widespread disruption. With the scope and scale of Cloudflare's operations,

when the firm's network goes down, the entire internet feels the impact.
