Arbitrum is the second-largest cohort in the cluster: 7 no-key providers including the Arbitrum Foundation's own `arb1.arbitrum.io/rpc`, and one of the few chains where Lava and MeowRPC still compete on a free tier. Foundation endpoints are documented best-effort, and our data shows what that means in practice: a respectable median with a p99 roughly ten times worse. Every provider answers the identical `eth_getBlockByNumber` probe every 60 seconds from us-east, eu-west and Singapore.
