Must not say

Anything that blames Google✓ Not said

Decided by provenance, not by how convincing the text sounds

CONFIRMED only with an organisation's own channel about itself or our internal systems (claims about us). REPORTED needs 2+ independent non-official sources, 1 monitor / press source, or 1 official source about someone else; anything else is at most UNCONFIRMED. CONFLICTING when credible sources disagree (both kept). UNKNOWN for questions nothing answers. A provider's status page outranks its other channels.
