How reliable is your node?

0xArc reports that RPC calls to blockchain nodes succeeded on average 78.5% of the time between 1 August and 20 October 2024, based on 1,492,103,937 requests, of which 1,171,952,063 succeeded and 320,793,140 failed. The article says performance varies by chain, provider, and method, with Polygon averaging about 60% success in August before rising to 80%+ in more recent weeks. It also says one provider, referred to as "orange provider," was among the most reliable overall but had sharp drops in archive node performance on Ethereum for almost a month. Pricing reportedly differs by up to 10 times per provider, chain, and method.
