Nerval's Lobster writes: "Amazon’s explanation for the problem that took down Netflix and other sites on Christmas Eve: human error. The Web giant blamed an unnamed developer who ran a maintenance process against state data used by the company’s Elastic Load Balancers, or ELBs. That mistake cascaded into other areas. At its peak, 6.8 percent of the company’s ELBs were affected—which might not sound like a lot, but they were balancing loads across multiple servers. Netflix was forced to apologize for the outage, publicly pinning the blame on AWS infrastructure. Amazon’s mea culpa highlights two areas in which the company can improve: access to its infrastructure, and disaster recovery (even if that disaster was self-inflicted)."
