Alexandria Incident

Alexandria Incidents are massive losses of data that intentionally or unintentionally take down part or the whole of a service's data at once. Geocities died intentionally, and the loss was the death of the whole service, and thus is considered an A type Alexandria Incident. The Myspace Data Loss Incident was unintentional, and was the loss of only a portion of the service, and thus is considered a B type Alexandria Incident. The Tumblr porn ban was intentional, and was a loss of only a portion of the service, and is thus a C type The Theoretical D type, where the data loss was unintentional and resulted in service wide data loss happens usually to small scale services, or large services in their early days, I do not know of many good examples of this if any The name, Alexandria Incident, comes from the burning of the library of Alexandria.
