  • CDN & security companies like Akamai actually have data centers designed to intercept and “scrub” DDoS traffic. Akamai has a few dozen of them around the world. From their website:

    Prolexic is the industry pioneer in cloud-based DDoS protection. Network traffic is directed in one of two ways via a border gateway protocol route advertisement change or DNS redirection (A record or CNAME record). Available as an always-on or on demand service, Prolexic offers flexible integration models based on the needs of a customer’s desired security posture across hybrid origins. With global high-capacity scrubbing centers in 32 metro locations, Prolexic can stop attacks closer to the source to maximize performance for users and maintain network resiliency through cloud distribution. Traffic is routed via anycast through the closest scrubbing center, at which the Akamai SOCC deploys proactive and/or custom mitigation controls designed to stop attacks instantly — ensuring fast and accurate DDoS defenses. Clean traffic is then returned to the customer origin via Generic Routing Encapsulation (GRE) tunnels, Layer 2 VLAN connections, and/or VIP-to-origin back-end mapping.
















  • This is one of the many edge cases that I’ve been convinced will keep self driving cars from becoming mainstream unless/until true AGI is achieved.

    A few years ago I stopped at a red light next to a construction site. I was watching the traffic light, so at first I didn’t notice a cop at the construction site trying to wave me through the red light. He finally took a few steps towards me and yelled to get my attention. Only then did I realize he was waving me through, so I did just that. I seriously doubt any current self driving car would recognize a police officer (and not just a random pedestrian) that’s overriding the traffic signal like that.

    Another edge case, coincidentally at the same intersection a few years earlier was when there was a car fully engulfed in flames as I drove up. I could hear sirens in the distance, and the cars in every direction were making sure to safely get out of the way of the approaching fire trucks. At least one or two cars cautiously crossed on the red to get out of the way. Again, I doubt any current self driving car would have navigated that situation anywhere nearly as well as a human.
