Ever changed a domain setting and wondered why your emails vanished or your website stopped showing the right version? This episode breaks down the real reasons behind DNS propagation delays and what you can do to avoid disaster.

📌 In this episode, Charly explains:

✅ What DNS propagation really is (hint: it's not instant)

✅ Why your changes take time to spread across the internet

✅ What TTL (Time to Live) means and how it affects your updates

✅ Best practices before migrating websites or email servers

✅ Tools like “What's My DNS” and “MXToolbox” to track changes

✅ Why caching (browsers and ISPs) can trip you up

🛡️ Avoid lost emails, broken sites, and confusion by understanding the pull nature of DNS updates and planning ahead.
