The TLD .ga is undergoing a change of ownership. Here is a press release talking about domains under .ga:
"ANINF estimates that there are currently over 7 million domain names in stock in the .ga name base. However, independent bodies consider that there is widespread technical abuse on ‘.ga’ domain names. As part of this switch-over operation, several million domain names will be deleted as the previous operator has not provided the data that concern them."
I hope that helps.
