Glassnode
Glassnode has launched a live latency monitor measuring real-time round-trip times from probes worldwide to the trading infrastructure that matters most for HFT, market making, and MEV: Hyperliquid validators, every voting Solana mainnet validator (~760 nodes) including Jito Block Engine regional endpoints, SUI validators with Mysticeti time-to-quorum metrics, the Arbitrum One and Robinhood Chain sequencers, the major centralized exchanges across spot, perps, and options, plus Pyth Lazer, Chainlink Data Streams, and Switchboard Crossbar oracle gateways.
The numbers the channel highlight for Robinhood Chain, which produces a block every 100 ms, frame how sharply geography dominates queue position: Ohio sits at 3 ms, Virginia 18 ms, Chicago 27 ms, London 91 ms, Tokyo 140 ms, and Sydney 200 ms. That is up to two full blocks of lead time for US-based traders over Asian and Oceanian counterparties, an edge that is structural, not informational.
Why it matters
For trading firms chasing first-look execution on perps, tokenized stocks, or oracle-dependent prices, physical distance to the matching engine or sequencer routinely dominates total latency. A server in the wrong city can lose by tens to hundreds of milliseconds, which is enough to surrender every arb and MEV opportunity to better-located competitors. The monitor publishes continuous measured numbers so operators can stop guessing about hosting decisions and start pricing them.
The Arbitrum One and Robinhood Chain sequencer measurements are especially load-bearing because both chains order transactions strictly by arrival at a single machine, with no fee-based priority. Distance is queue position, full stop, which makes the latency from any probe to arb1-sequencer.arbitrum.io or sequencer.mainnet.chain.robinhood.com a direct read on competitive standing for Timeboost bidders and first-come-first-served flow.
Market impact
Probes are deployed worldwide across Asia, Europe, the Americas, and Oceania/Africa on Fly.io and AWS bare-metal instances.

Frequently asked questions
-
What does the Glassnode Latency Monitor actually measure?
It measures real-time round-trip latency from probes worldwide to Hyperliquid validators, every voting Solana mainnet validator (~760 nodes) with Jito Block Engine regional endpoints, SUI validators including time-to-quorum, the Arbitrum One and Robinhood Chain sequencers, major CEXs across spot and derivatives,…
-
Why does co-location matter for crypto trading?
Physical distance to matching engines and sequencers routinely dominates total latency, costing tens to hundreds of milliseconds. On chains with FCFS ordering like Arbitrum One and Robinhood Chain, distance is effectively queue position, so latency numbers translate directly into missed MEV and arbitrage opportunities.
-
How big is the edge from being close to the Robinhood Chain sequencer?
Per the channel's data, Ohio sits at 3 ms, Virginia at 18 ms, Chicago at 27 ms, London at 91 ms, Tokyo at 140 ms, and Sydney at 200 ms. With blocks produced every 100 ms, that is up to two blocks of lead time for US-hosted traders over Asian and Oceanian counterparties.
-
Which Solana-specific metrics does the monitor expose?
It tracks QUIC handshake latency to every voting mainnet validator, real-time leader-rotation tracking, stake-weighted best-co-location rankings, and Jito Block Engine paths across all 8 regional endpoints (Amsterdam, Frankfurt, London, Dublin, New York, Salt Lake City, Tokyo, Singapore).
-
Where are the probes deployed?
Probes run on Fly.io and AWS bare-metal across Tokyo (multi-AZ), Seoul, Hong Kong, Singapore, Amsterdam, Dublin, London, Frankfurt, Ashburn, Ohio, Chicago, San Jose, São Paulo, Sydney, and Johannesburg, giving global coverage across Asia, Europe, the Americas, and Oceania/Africa.
