AWS Went Down Not Impact Ethereum, Majority Nodes Hosted on Cloud Remain a Concern

Amazon Web Services (AWS) suffered a minor outage but there was no impact on Ethereum network nodes which largely rely on Amazon’s hosting. On June 13, the cloud service provider went down temporarily for around three hours. The outage seems limited to US-EAST.

The majority of 8,512 active Ethereum nodes are in the hands of centralized web providers like Amazon Web Services (AWS), which could “expose Ethereum to central points of failure”.

Three major cloud providers account for 75% of hosted nodes on the Ethereum Mainnet, with over 64% of that coming from Amazon Web Services (AWS), over 5.6% from Hetzner and 5.2% from Google Cloud.

High costs to run infrastructure make it more likely that nodes would run infrastructure with cloud computing providers (i.e AWS) - making Ethereum more exposed to central points of failure.
