AWS is rolling out a new feature aimed at enhancing DNS resilience in response to frequent outages in its US East region. Customers from regulated sectors, including banking and FinTech, expressed the need for a reliable way to make DNS changes during unexpected disruptions. The new capability offers a 60-minute recovery time objective (RTO), allowing users to implement DNS adjustments and reroute traffic in a timely manner when issues arise. Despite this improvement, the 60-minute window still leaves room for significant outages and interruptions. AWS has faced a history of problems in US East, with notable incidents like the DynamoDB issue on October 20th and other service disruptions in 2021 and 2023. Analysts from Gartner have pointed out that US East poses a vulnerability within AWS’s infrastructure, as its massive scale can lead to more pronounced issues compared to other regions. Although AWS previously claimed that US East’s reliability is comparable to its other regions, the ongoing challenges have prompted changes. The introduction of this DNS backstop reflects AWS's acknowledgment of its past shortcomings and a step toward mitigating the impact of future outages. The company is under pressure as competition intensifies in the cloud market, and improving service resilience is essential for retaining customer trust.
