Building resilience: Inside AWS’s nine million kilometers of fiber-optic cabling

AWS has built an extensive global network infrastructure spanning over nine million kilometers of fiber-optic cabling, which could reach from Earth to the Moon and back over 11 times. The network is designed with resilience and redundancy as core principles.

• Spans 38 AWS Regions and 120 Availability Zones
• Uses multiple redundant pathways to ensure continuous connectivity
• Operates diverse routes across major subsea corridors worldwide
• Employs "design with failure in mind" approach to maintain service during disruptions
• Continuously upgrades infrastructure, using 400 Gigabit Ethernet technologies
• Implements robust security measures including encryption and threat detection

The network is strategically expanded based on customer needs, preparing for future technological demands like AI computing and emerging technologies, while maintaining global connectivity and resilience.
