Longtime Slashdot reader belmolis writes: Part of New York City's 911 emergency system was offline from about 3:13 a.m. to 10 a.m. on August 18th due to a software update, according to Medical Daily. Of 5,659 calls to the Bronx call center during that period, about 1,700 calls connected but could not be heard by emergency operators. Some were rerouted to other call centers, but an estimated 400 human callers never got through. The potentially serious consequences of delayed response to emergencies are not yet known. The city did not notify the public and only released information when journalists inquired. How buggy software came to be installed on a running system is not yet known. The early-morning software update was pushed by Motorola, though exactly what it changed or why it caused the failure remains unknown. The city is still investigating whether the update was adequately tested and whether the same software release was deployed elsewhere.
