• Hacker News1AWS Multiple Services Down in us-east-1AWS experienced a major outage in the US-EAST-1 region on October 20th, affecting 82 services including EC2, RDS, Lambda, and DynamoDB. The issue was traced to DNS resolution problems and was gradually resolved over several hours, with most services recovering by early morning.Identity and authentication failures during outages:Companies discovered they couldn't failover to other regions because security systems like AWS Identity Center were only configured in us-east-1, creating circular dependencies where authentication systems needed the same region they were trying to escape from.Multi-region architecture and resilience strategies:Discussion of building truly resilient systems across multiple AWS regions, with some users successfully weathering the outage through proper multi-region setup while others learned hard lessons about single points of failure.AWS reliability and vendor lock-in concerns:Users questioning AWS's reliability claims and considering diversification strategies, with some planning to move away from AWS entirely while others debated whether multi-cloud approaches actually improve overall uptime.
• Reddit science1Using 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
