"Cloudflare is uniquely positioned to host an Ethereum gateway, and we have the utmost faith in the products we offer to customers. This is why the Cloudflare Ethereum gateway runs as a Cloudflare customer and we dogfood our own products to provide a fast and reliable gateway. The domain we run the gateway on (https://cloudflare-eth.com) uses Cloudflare Workers to cache responses for popular queries made to the gateway. Responses for these queries are answered directly from the Cloudflare edge, which can result in a ~6x speed-up.
We also use Load balancing and Argo Tunnel for fast, redundant, and secure content delivery. With Argo Smart Routing enabled, requests and responses to our Ethereum gateway are tunnelled directly from our Ethereum node to the Cloudflare edge using the best possible routing."
