Because caches have not caught up
A record you changed five minutes ago can still resolve to the old value for hours: resolvers keep the answer for as long as the record's TTL told them to, and the previous TTL is what applies to the change. If a checker shows the old value, the usual answer is that nothing is broken and the wait is not over.
- The old TTL governs how long the old answer lives
- Lower the TTL before a planned move, not after
- Mail can follow a different path than the website
This reads the public DNS, so it can only see what is published: split-horizon setups, records behind a proxy, and anything served from an internal resolver will look different from inside your own network. It is a diagnostic, not a monitor — it answers what the record is now, not whether it changed overnight.
