Making the .au trust layer visible

.au Domain Observatory (.auDO) is an independent public-interest observatory for the .au domain ecosystem. It repeatedly observes a fixed panel and preserves visible DNS, registration, mail and infrastructure signals over time.

Repeated observation shows what is visible now, what changed and what persisted. .auDO does not score organisations, claim whole-namespace coverage or infer incidents from public signals alone.

Daily observation is active across a fixed 100-domain .au panel. Reporting focuses on visible signals, recurring patterns, and changes over time.

Follow the evidence

What do you want to understand?

Start with the question you are trying to answer. Each view keeps the evidence close while adding only the context needed for that task.

Current posture

What is visible across the panel now?

See the latest aggregate posture for public DNS, registration, mail and infrastructure signals.

Change over time

What changed, and what persisted?

Use dated and longitudinal reports to follow observed movement across repeated collection windows.

Cohort lenses

What does the evidence look like through a cohort lens?

Explore curated, sometimes overlapping groups of panel domains without treating them as rankings or whole-sector assessments.

Observation scope

Which domains are being repeatedly observed?

See the fixed panel, its composition and the stewardship model that keeps repeated observation comparable over time.

How to read this visual

A symbolic view of repeated observation across selected points in the Australian domain namespace.

.auDO observes the same panel over time, preserves what was seen, and compares changes so patterns can emerge carefully.

A single lookup shows a moment. Repeated observation shows change and persistence.

Understand the evidence

What do these signals mean?

Move from plain-language meaning to the evidence definition and then to the method used to collect and interpret it.

Read the evidence with context

Signals define what .auDO observes, Explainers provide durable plain-language context, and Methodology describes how observations are collected, preserved, compared and published.

Common questions

A few boundaries worth knowing

These answers set expectations before you interpret .auDO evidence or move into the deeper analytical views.

Can I use .auDO to look up any .au domain?

No. .auDO repeatedly observes a fixed panel of selected .au domains so that visible change and persistence can be examined over time. It is not an on-demand domain checker.

For a point-in-time view of public DNS, mail, web delivery, certificate and registration signals for a specific domain, use ThreatScope Check.

Does State of .au describe the whole .au namespace?

No. State of .au describes visible posture and observed change across the fixed .auDO observation panel. It is not a measurement of every .au domain or the broader internet.

State views use the latest panel evidence and defined observation windows to show current posture and bounded movement.

Does an observed change mean something is wrong?

No. A visible change can reflect ordinary technical, provider or administrative activity. .auDO preserves what changed and adds context where the evidence supports it.

An observation does not by itself establish an incident, compromise, compliance failure or organisational risk.

About .auDO

Independent observation, bounded claims

.auDO preserves public domain-layer evidence across a selected fixed panel as a public-interest resource. It is not a registry authority, regulator, assurance service, incident detector or organisational risk-rating product.
