 ## Autonomous Edge
 
-The Cloudflare Autonomous Edge is powered by the denial-of-service <GlossaryTooltip term="daemon" prepend="A daemon is ">daemon</GlossaryTooltip> (`dosd`), which is a home-grown software-defined system. A `dosd` instance runs in every single server in every one of [Cloudflare global network's data centers](https://www.cloudflare.com/network/) around the world. These `dosd` instances can detect and mitigate DDoS attacks autonomously without requiring centralized consensus. Cloudflare users can configure this system through [DDoS Attack Protection managed rulesets](/ddos-protection/managed-rulesets/).

 Another component of Cloudflare’s Autonomous Edge includes the [Advanced TCP Protection](/ddos-protection/advanced-ddos-systems/overview/advanced-tcp-protection/) system. This is Cloudflare's TCP state tracking machine for detecting and mitigating the most randomized and sophisticated TCP-based DDoS attacks in unidirectional routing topologies — such as the case of [Magic Transit](/magic-transit/). Advanced TCP Protection is able to identify the state of a TCP connection and then drops, challenges, or rate-limits packets that do not belong to a legitimate connection.

 Complementary to the Autonomous Edge, Cloudflare’s entire global network is overwatched by a global version of `dosd`. This component protects Cloudflare’s entire global network by detecting and mitigating globally distributed volumetric DDoS attacks.
 
-The centralized systems run in Cloudflare's core data centers. They receive samples from every global network data center, analyze them, and automatically send mitigation instructions when detecting an attack. The system is also synchronized to each of our customers’ web servers to identify their health and trigger any required mitigation actions.

+## Thresholds
+
+Thresholds vary for each rule and there are different thresholds globally and per colocation. Within a rule, the traffic is fingerprinted and the thresholds are per fingerprint, and it is difficult to know ahead of time which rules, colocations, or fingerprints your traffic generates, so the threshold numbers are not necessarily valuable.
+
+Instead, Cloudflare's DDoS Protection system provides the sensitivity adjustment. If you experience a false positive, you can decrease the sensitivity. You can also use the `Log` action to help find an appropriate sensitivity level. You can decrease the sensitivity while in `Log` mode until the rule no longer matches.

+[Adaptive DDoS Protection](/ddos-protection/managed-rulesets/adaptive-protection/) also learns your unique traffic patterns and adapts to them to provide better protection against sophisticated DDoS attacks on layer 7 and layers 3/4.

Additionally, the systems may flag suspiciously-looking incoming traffic from legacy applications, Internet services, or faulty client applications as malicious and apply mitigation actions. If the traffic is in fact legitimate, the mitigation actions can cause service disruptions and outages in your Internet properties.
