What is the ruling on saying, "You are divorced" to one's wife online in a moment of anger?

A husband's statement to his wife, "You are divorced," effects a divorce, even if made in anger, unless the anger is so severe that it leads to loss of consciousness. The wife's presence is not a condition for the divorce to occur. So, if a husband says to his absent wife, "You are divorced," via the internet, a single revocable divorce takes place, unless it is the third divorce. If the statement is in writing, divorce does not occur unless there is an intention to divorce.
