# Reachability across ten .bank domains spiked 6.5 times the norm on August 16

A single-day surge across regulated-finance domains landed 4.3 standard deviations above the 28-day average, with named institutions among those affected.

Reachability changes across ten domains carrying the regulated .bank suffix ran 6.5 times their 28-day average on August 16, 2026, with the reading sitting 4.3 standard deviations above that baseline, according to DRM3's DomainDrift Trends instrument.[^1]

A movement that far from the mean is not background noise. The read here is that something coordinated - a configuration push, a provider migration, or an infrastructure event - touched this specific suffix on a single day, rather than changes rippling in gradually across unrelated actors.

The DRM3 DomainDrift Trends instrument identified six of the ten domains by name: avb.bank, bankiowa.bank, banknorth.bank, btcbank.bank, clearfork.bank, and dollar.bank. The remaining four were not named in the measurement.

What is missing from the record is the direction of those reachability changes - whether domains went up, went down, or cycled - and whether any single DNS provider, hosting platform, or infrastructure event appears across the affected names. That detail would go a long way toward explaining whether August 16 was a planned rollout or something less orderly.

## What this stands on

1. reachability changes across regulated-finance-suffix domains ran 6.5x the 28 day average on 2026-08-16 (10 domains). The reading sits 4.3 standard deviations above the 28-day average. The domains include avb.bank, bankiowa.bank, banknorth.bank, btcbank.bank, clearfork.bank, dollar.bank. (DomainDrift, DomainDrift trends, claim on record)
