WHOIS is a tool that permits people to access information about a particular domain name.
In some cases the information in this system is not updated right away in “real time”. For example, if a domain name has transferred ownership, it’s possible this fact wouldn’t be visible in WHOIS for 15 minutes.
The Tucows WHOIS information has an update delay of around 15 minutes. In general, if you need to be certain that your domain name information is correct we recommend you use the Tucows WHOIS 15 minutes after you make a change.
