This breakdown video chapters the disaster (0:00 Summary, 5:30 Dynamo DNS meltdown, 13:41 EC2 errors, 16:16 NLB chaos), links to AWS’s official RCA, and—because why not—sprinkles in a buffet of backend courses, tutorials, and Hussein’s socials for anyone keen to level up while waiting for the next cloud apocalypse.
