Based on its unique architecture, Amazon S3 is designed to exceed 99.999999999% data durability.

I missed this yesterday, but AWS Middle East (UAE) (me-central-1) has been having issues due to the war.
"At around 4:30 AM PST [2026-03-01], one of our Availability Zones (mec1-az2) was impacted by objects that struck the data center, creating sparks and fire. The fire department shut off power to the facility and generators as they worked to put out the fire."
"**Mar 01 10:46 PM PST** We can confirm that a localized power issue has affected another Availability Zone in the ME-CENTRAL-1 Region (mec1-az3)."
This might be the first time AWS has ever had separate, serious outages affecting multiple AZs simultaneously, if you exclude the many many outages where a region-level service like S3 goes down due to a software issue.

Edit: I didn't scroll down! Middle East (Bahrain) also has an affected AZ.
"**Mar 01 11:09 PM PST** We are investigating connectivity and power issues affecting APIs and instances in a single Availability Zone (mes1-az2) in the ME-SOUTH-1 Region due to a localized power issue."
