The document that makes recovery possible.
WHAT TO RECORD
Where the domain is registered and when it renews Where hosting is and what plan What the site is built on Where backups are What email is used and where What accounts exist with suppliers and services Who has access to what Key contacts
WHY
In a crisis, nobody remembers.
And if you are unavailable, nobody knows.
WHAT NOT TO PUT IN IT
Passwords in plain text.
Reference where they are, in a password manager.
WHERE TO KEEP IT
Not on the server Not only in email Somewhere reachable when systems are down
A printed copy in a safe place, plus a digital one elsewhere.
HOW DETAILED
Enough that someone competent could take over.
WHAT TO UPDATE
Whenever anything changes.
An out-of-date record misleads in a crisis.
HOW OFTEN TO REVIEW
Annually at minimum.
WHAT THIS ENABLES
Recovery, handover, and continuity if you are unavailable.
