DNS changes aren't always instant — here's what to expect.

• Typical: most changes take effect within a few hours.
• Maximum: allow up to 24–48 hours for the change to reach everyone worldwide.
• Why: networks cache DNS records for a set time (the TTL), so older cached values linger until they expire.

Tip: During propagation, you might see the new site while a colleague still sees the old one — that's normal. Clearing your browser cache (article 199) or trying another device can help. Tools like a DNS checker let you watch propagation progress.
