Highest profile software failures of 2012
Posted on 19 December 2012.
SQS compiled a list of the worst software failures over the past 12 months. This year’s annual survey is based on major software failures throughout 2012 and highlights the continuing problems faced by the financial and banking sector, which have dominated the software glitch top ten lists over the past three years.

In the 2012 survey, financial services software glitches represent five of the top ten. Legacy systems in banks and trading firms are not being updated or replaced due to financial constraints and this is one major cause of failure.

1. Software glitch costs trading firm $440million in 45 minutes

A trading firm’s newly-installed software resulted in a $440 million loss after it rapidly bought and sold large volumes of over a hundred different stocks in 45 minutes using a flawed software algorithm that bought the shares at market price then sold at the bid price - instantly losing a few cents on each trade. The rapid trades pushed the price of the stocks up, resulting in spectacular losses for the trading firm when it had to sell the overvalued stocks back into the market at a lower price.

2. Leading securities markets’ operator

A stock trading business launching its initial public offering on its own trading system was forced to withdraw its IPO after an embarrassing computer glitch caused a serious technical failure on its own exchange. A system problem occurred as soon as the exchange tried to open the ticker symbol of the stock, failing to roll into a continuous trading pattern as it was supposed to, halting the trading on the stock before it had even started trading.

3. Stock Exchange IPO trading of social media giant falls flat

Technology problems affected trading in millions of shares of a popular social media website, after software glitches caused a malfunction in the trading system’s design for processing orders and cancellations, meaning orders were processed incorrectly, if at all. Trades in as many as 30 million shares were affected by the glitch.

4. US elections’ vote glitch sees nomination problems

Computer problems drew complaints across the US during the 2012 elections, with numerous problems with voting machine glitches reported by voters. An example was touchscreen errors automatically changing the vote from one candidate to another and not allowing voters to reselect or correct the error.

5. Airline’s software glitch strands travellers for the third time

For the third time in 2012, a computer glitch wreaked havoc on thousands of travellers with a US airline, delaying flights for hours. A glitch in the dispatch system software resulted in hundreds of delayed flights across the US and internationally. The two hour outage held up 636 of the 5,679 scheduled flights and resulted in 10 flights being cancelled altogether.

6. Security staff shortage at international sports event

An internal computer systems problem resulted in miscalculation of the number of security staff required to support an international sports event this summer. This internal staff rostering glitch resulted in members of the armed forces being drafted in to act as security staff.

7. Teething problems for new revenue service software system

After upgrading its software and revenue service system, at an estimated cost of $1.3 billion through 2024, to promote e-filing of tax returns, the US revenue service saw delays in handling electronic tax returns, with 85 per cent of refunds delayed by 23 days+.

8. Gambler loses winnings to computer virus

A gambler, who was under the impression he’d won just over $1 million, was told by a High Court that, despite his anticipated windfall showing in the online game he had played, he was not a millionaire after all. A software error mistakenly reported his winnings as much higher than they actually were and, due to this contingency being covered in the game’s terms and conditions, he could not legally claim his anticipated prize.

9. Utility customers in the dark over late notice and incorrect payment charges

An Australian energy company sent thousands of customers late payment charges for bills they didn't receive due to a computer glitch, while a Germany utility company overcharged 94,000 of its customers due to a computer glitch that incorrectly charged exit fees, costing the energy supplier $2.24 million in settlement payouts.

10. Leap year bugs disrupt banking and healthcare payment systems

A leading multinational corporation’s cloud computing service outage, which affected Governments and consumers, was caused by the additional day in February this year. The same leap year date bug also affected an Australian payment system used by the health industry, resulting in 150,000 customers being prevented from using private health care cards for medical transactions for two days.
