I didn't want to make anyone upset with this tool. The current version of the service is based on the DNS lookup, which is not always accurate. The errors may happen when a domain does not have a name server record specified or it is in the a redemption period. The current version is an experiment that checks if such a tool can be useful for people. All the received feedback will be used to improve it. Using more reliable approach of domain availability checking for sure has the highest priority.
