The Worst Computer Bugs of 2011

By Jesus Diaz on at

Earlier this year a man lost a £36 million jackpot when a casino alleged a "software glitch" on the slot machine. Well, that's nothing compared to the backlog of £6 billion in unprocessed payments that happened in Japan on March.

Here are the top five worserest, most expensive computer glitches of 2011, according to Software Quality Systems, a UK company specialised in this kind of thing:

1. Financial firm services AXA Rosenberg made investors lose £140 million because of a software glitch in their investment model. They hid the bug from their clients, so they had to pay back that amount plus a £16 million fine to the US Securities and Exchange Commission. Oh you cheeky 1 per cent bastards, you.

2. Car manufacturer Honda had to recall 2.5 million cars because of a bug that allowed vehicles to shift out of part and engine stalls. That's a lot of dope for some bad lines of code.

3. Japanese bank Mizuho Financial Group's clients experienced a software glitch that collapsed their ATM network and internet banking systems. The result was £1 billion in salary payment delays and £6 billion in unprocessed payments. Six billion. With B.

4. A £1.75 billion cloud computing US Army network failed miserably, leaving troops unable to perform the most simple tasks. The system slowed down to a crawl when multiple users were logged in and their search engine as not compatible with the army's existing search software. I wonder what was the final amount of time and money lost, not to mention the endangerment of lives. They are not telling yet.

5. Here's a good one—for those who were able to enjoy the glitch. A Commonwealth Bank's ATM network bug caused the machines to spit large amounts of money to random people. They don't know how much money people took—or they are not saying. Police said that taking that money was a crime and actually arrested two people. No word about the hundreds who took the money and ran.
