Hacker News1 Today is when the Amazon brain drain sent AWS down the spoutA major AWS outage in the US-East region was caused by DNS issues affecting DynamoDB, disrupting much of the internet for hours. The article argues this reflects a talent exodus at AWS, with experienced engineers who understood complex failure modes leaving due to layoffs and return-to-office policies, leaving newer teams without critical institutional knowledge to quickly detect and resolve such incidents. Amazon's talent retention crisis: Discussion centers on Amazon's high turnover rates and difficulty retaining skilled engineers. Multiple users share negative experiences, with many lasting under 3 years. Internal research suggests Amazon may "deplete available labor supply" in some regions due to their burn-through rate.AWS outage response time concerns: Users debate whether 75 minutes to diagnose the root cause was reasonable for a major AWS outage.

Users compare this to manufacturing lessons about experience being non-fungible.
Reddit science1 Using scented products indoors changes the chemistry of the air, producing as much air pollution as car exhaust does outside, according to a new study. Researchers say that breathing in these nanosized particles could have serious health implications.Using scented products indoors, such as flame-free candles and wax melts, can create significant indoor air pollution comparable to car exhaust. Research by Purdue University found these products release nanosized particles that can penetrate deep into lungs and potentially enter the bloodstream, posing serious respiratory health risks. Misleading title scope: Discussion about how study only focused on wax melts but title suggests all scented products, with debate about whether findings could logically extend to other scented itemsHealth concerns from chemist: A chemist's perspective against using scented products leads to sharing of personal health impact stories, from COPD to cancer cases, and debate about necessity of artificial scentsAir purification solutions: Discussion of HEPA filters and other air purification methods as solutions, with debate about effectiveness against different types of pollutants like VOCs and nanoparticles
