AWS said the damage to the infrastructure had extended across several Availability Zones; for data and resources that were not migrated, the provider sees no recovery option in Bahrain.<\/p>\n<h2 style=\"margin-top:64px;margin-bottom:20px;padding-top:16px;\">From the initial incident to an unusable region<\/h2>\n<p>AWS said on 2 March 2026 that a drone strike in the immediate vicinity had damaged buildings and the power supply in Bahrain. According to AWS, firefighting work partly caused water damage. <a href=\"https:\/\/www.reuters.com\/world\/middle-east\/amazon-cloud-unit-flags-issues-bahrain-uae-data-centers-amid-iran-strikes-2026-03-02\/\">Reuters<\/a> reported that day on damage to data centers in Bahrain and the United Arab Emirates.<\/p>\n<p>After the initial incident in Bahrain in March, AWS recommended migrating to other regions. In April, another Availability Zone failed; that made the region unusable, <a href=\"https:\/\/www.reuters.com\/world\/middle-east\/amazons-aws-is-unable-restore-access-bahrain-one-uae-cloud-data-zone-after-war-2026-09-15\/\">Reuters<\/a> reports.<\/p>\n<h2 style=\"margin-top:64px;margin-bottom:20px;padding-top:16px;\">In the Emirates, one zone remains inaccessible<\/h2>\n<p>In the United Arab Emirates, AWS cannot restore resources and data from the Availability Zone <strong>mec1-az2<\/strong>, a single zone within the region. In the other affected zones in the Emirates, AWS is continuing the work and replacing infrastructure there, as <a href=\"https:\/\/www.reuters.com\/world\/middle-east\/amazons-aws-is-unable-restore-access-bahrain-one-uae-cloud-data-zone-after-war-2026-09-15\/\">Reuters<\/a> reports.<\/p>\n<h2 style=\"margin-top:64px;margin-bottom:20px;padding-top:16px;\">What does Multi-AZ do about region-wide damage?<\/h2>\n<p><strong>What is Multi-AZ?<\/strong> Multi-AZ refers to running a service across several Availability Zones within one region. Availability Zones are separate locations within that region. Which data and components are stored redundantly depends on the service and its configuration. Distribution across zones protects against the failure of a single zone; a copy outside the region is not included.<\/p>\n<blockquote style=\"margin:36px 0;padding:0;\">\n<p style=\"font-size:1.35em;line-height:1.45;font-style:italic;font-weight:500;\">AWS said: The damage exceeded the limits that regional and Multi-AZ services are designed for.<\/p>\n<p style=\"font-size:0.85em;color:#666;font-weight:600;\">AWS, as quoted by Reuters<\/p>\n<\/blockquote>\n<p>When a single damaging event affects several zones within a region, distributing resources across those zones is not enough to restore operations. To restore data and services, the operator needs a copy or an independent backup in another location.<\/p>\n<h2 style=\"margin-top:64px;margin-bottom:20px;padding-top:16px;\">AWS leaves the fate of the data unclear<\/h2>\n<p><a href=\"https:\/\/thenextweb.com\/news\/aws-bahrain-uae-cloud-zones-cannot-restore-war-damage\">The Next Web<\/a> reported on 15 September 2026 that AWS has not said publicly whether customer data without a backup outside the affected zones is permanently lost.<\/p>\n<p>AWS says it is helping Bahrain customers run their operations in other regions. Where backup copies exist, the provider helps customers resume operations; in other cases, AWS points to further solutions but gives no details.<\/p>\n<h2 style=\"padding-top:64px;margin-bottom:20px;\">Frequently asked questions<\/h2>\n<details>\n<summary><strong>What is Multi-AZ?<\/strong><\/summary>\n<p style=\"margin:8px 0 4px 24px;color:#555;line-height:1.6;\">Multi-AZ primarily protects against the failure of a single Availability Zone.
