The new name server settings are activated but I still see the old data? How is this possible?
Name servers around the globe cache (store) data to increase their speed. After you have changed the records in the Hostbasket name servers, it takes a while before other name servers around the globe read these new settings. Only once the cached data (temporary copies) has expired, will name servers search for more up-to-date information. In most cases your changes will be active within 24 hours; this delay is defined in the TTL (Time To Live) of the DNS record.
