The Internet

The Internet is a global system of interconnected computer networks used by Muggles for communication and information sharing. Within the context of the Wizarding world, it is a piece of technology that is almost entirely unused and unknown. The magical community's self-imposed separation from the Muggle world, combined with a fundamental incompatibility between magic and electronics, means that wizards and witches rely on their own established methods for communication and research, rendering the Internet redundant in their society.

The primary reasons for the absence of the Internet in the Wizarding world are both cultural and practical. The wizarding society is deeply traditional and shows little interest in adopting Muggle conveniences, often viewing them as quaint or inferior alternatives to magical solutions. More fundamentally, areas with a high concentration of ambient magic, such as Hogwarts School of Witchcraft and Wizardry, interfere with the functioning of complex Muggle electronic devices. This magical interference causes such technology to malfunction, making it impossible to operate computers, and by extension, access the Internet in most magical locations (Pottermore). Wizards have their own highly effective, and often instantaneous, methods for communication and information retrieval that they see no reason to replace:
