![What You Need To Know About the Colonial Pipeline Attack #shorts
Colonial Pipeline is recovering from a ransomware cyberattack. With any attack that has this level of visibility theres a ton of assumptions and people leaping to conclusions...especially around attribution.
We dont have a lot of information about the attack. Thats completely normal at this stage.
The team at Colonial Pipeline is working through their incident response process. Attribution doesnt happen until the later stages of that process (if ever!) but a critical step is containment.
Thats what prompted the pipeline closure and—while difficult—its good that they took that step to reduce any potential damage.
Ransomware very often tries to encrypt any and all systems it can reach. Stopping the spread most likely saved the team an even bigger headache down the line

![Can We Improve How Lyft Handled Service Discovery on AWS In 2016? (Reaction)
In late 2016, Lyft did an AWS This is My Architecture video. It was one of the first. In the video they explained how they tackled the problem of discovering what microservices were available and healthy in their environment.
Now, a few years later, I react to that video and see whats stood the test of time, what could be done simpler given todays technology, and generally critique the design against the AWS Well-Architected Framework in a mini AWS Well-Architected Review.
The original video: https://youtu.be/sjpP2ynkCbo
