THE SOFTWARE HORROR PICTURE SHOW
|AT&T Long Distance Service Fail, 1990
On January 15, 1990, one of AT&T's switching-stations in Manhattan crashed. Station after station across America collapsed in a chain reaction, until fully half of AT&T's network collapsed. The collapse was caused by a software flaw in the front-end processors of all 114 of its 4ESS switching-stations.
