+To compare the public endpoints above from your region, see [OpenChainBench / ink-rpc](https://openchainbench.com/benchmarks/ink-rpc), an open-source ([ChainBench/openchainbench](https://github.com/ChainBench/openchainbench)) probe that calls `eth_getBlockByNumber` on each keyless provider every 60 seconds from Paris, Virginia, and Singapore, and publishes p50 / p95 latency and availability.
