How did the Pulse chart illustrate the impact of the Cloudflare outage on latency and availability?

Question

The Pulse chart provided critical visual evidence of the Cloudflare outage's impact on network performance, specifically highlighting a significant spike in latency and a concurrent drop in availability. When juxtaposed with the Smart Load Balancing optimization chart, this data paints a clear picture of the disruption. The Smart Load Balancing chart demonstrates how the system dynamically shifted traffic away from Cloudflare to alternative Content Delivery Networks (CDNs), such as Akamai, in various regions. For instance, the chart shows several query spikes for Akamai within the United States, indicating that the system was actively rerouting requests due to Cloudflare's degraded performance. This active rerouting, evidenced by frequent swaps between Cloudflare and Akamai in the US, directly correlated with the latency spike and availability decrease observed on the Pulse chart for Cloudflare during the same 27-minute period on July 18th, 2020. This confluence of data underscores the real-time impact of the configuration error in Cloudflare's backbone network, which overwhelmed a router and led to an estimated 50% traffic drop across their network.
