Why does my TXT record lag behind after an edit?

Resolvers cache prior answers until TTL expires, so global visibility shifts gradually even after authoritative DNS updates immediately.

Should I lower TTL before a major DNS migration?

Temporarily reducing TTL helps receivers pick up new values sooner—plan the window with your DNS provider’s minimums and propagation constraints.

Time-to-live defines how long resolvers cache answers. Lower TTL before large migrations if your DNS provider allows controlled updates.

Use resolver tools that query authoritative servers and public caches—single-machine dig results can be misleading during propagation.

Major receivers may cache longer than your nominal TTL during incidents—plan overlapping validation windows.
