AWS Blockchain Tracker provides a post mortem analysis on the impact of the October 20th AWS outage on various chains. L1's such as Solana prove to be the least dependent on AWS, with L2's like Base being the most dependent.

AWS’s October 20, 2025 outage exposed how dependent parts of the crypto stack are on centralized cloud infrastructure. The incident began with a DNS-related failure affecting DynamoDB in AWS’s us-east-1 region and rippled into consumer apps, exchanges, and blockchain infrastructure. Coinbase said the disruption impaired multiple product lines, while Base reported reduced sequencer and RPC capacity and delayed transaction inclusion until AWS recovery progressed. The broader takeaway from post-mortem analyses is that Layer-2 networks and other scaling systems appear more exposed to cloud-provider single points of failure than some Layer-1 networks. Metrika’s analysis says the outage had its clearest blockchain impact on Base, with block space utilization falling sharply, finalization times spiking, and throughput dropping during the incident window, while also noting that Solana showed comparatively low dependence on AWS and less visible impact. The story matters because it highlights that decentralization at the protocol level does not eliminate operational risk if critical infrastructure such as sequencing, RPC endpoints, or node hosting is concentrated in one cloud environment.
