History

Historical Context

Since its 2006 launch, Amazon S3 has powered services like Netflix and Reddit, but recurring AWS outages—such as the 30-minute us-east-1 failure on 8 August 2011 and the multi-hour S3 outage on 28 February 2017—show the platform’s systemic fragility. Each incident forces dozens of high-traffic sites offline, prompting firms to diversify routing and demand stronger SLAs.
