Amazon.com IncAWS says it cannot restore its Bahrain cloud region or a damaged UAE availability zone, undermining the reliability of its infrastructure capacity.

Amazon shares fell approximately 1.5% to $249.65 Tuesday after Amazon Web Services said it cannot restore its Bahrain cloud region or one damaged availability zone in the United Arab Emirates, damage the company said exceeded what the regional architecture was designed to withstand following the Iran war. The Bahrain disruption cut across multiple availability zones, challenging a core premise of AWS infrastructure redundancy; most customers shifted workloads elsewhere before a second zone went offline, but resources that were not moved remain unavailable. AWS expects another update on Bahrain in early 2027, while restoration progress for the affected UAE zone is expected within the coming months. The financial stakes are significant: AWS generated $42.23 billion of second-quarter revenue and $16.62 billion of operating income, implying a roughly 39.4% operating margin, profitability that depends partly on selling reliability at enormous scale. As Amazon builds more AI-heavy data-center capacity worldwide, exposed regions may require wider geographic separation, stronger physical protection and more aggressive cross-region backup systems, investments that could raise costs but also make AWS harder to displace.
