The magical powers that define when and if your internet will work for no logical reason. They are occasionally wooed by begging and/or excessive force to computer equipment (although the latter can also upset them beyond reconciliation).
I spent three hours trying to connect to Comcast and then suddenly the Internet Fairies smiled upon me.
An internet fairy is similar to the troll in that an individual anonomously pokes fun at unsuspecting individuals online. The distinction between the two can be made by the cute and endearing nature of the faerie that is practically harmless in nature.
