Best Colocation

Slot weighting is over the whole current epoch (the leader schedule for all 432k slots, ~2 days).
Probe latency is over only the last 90 minutes.

Unlike a fixed-destination exchange, Solana's leader rotates every 1.6 seconds across ~760 validators worldwide. Your latency to the network changes constantly — sub-millisecond when the leader is nearby, hundreds of milliseconds when it's across the globe. The weighted average reflects your expected latency across the full epoch, weighted by each validator's leader slot count.

Accurate for the current epoch (~2 days). For analysis across multiple epochs showing how colocation rankings shift over time, Glassnode historical data is available.

Weighted p99 is the stake-weighted p99 of each probe's handshake RTT to each validator over the last 90 minutes — the tail latency you should plan for, not just the median. Tail Gap is p99 − median; smaller is better (a tight distribution beats a slightly lower median with fat tails).
