- #78 Knight Capital wrote trading software billions of billions of dollars of transactions through their system everyday They would take large transactions and break them up in to smaller transactions to be more efficient. in 2012, made a change to their software. Repurposed a flag from 8 years ago. Tested rigorously.. and it worked, everything worked. Deployment time came – over night, everything looked good. The market opened and this happened.. Lost $440 Million loss in 45 minutes. Not because of a bug in the code, but because the updates were updated to 7 of their 8 servers. So the 8th server was going down this old code path and doing bad things.. They went bankrupt in 45 minutes They were so large, they were considered a “Market Mover” – so when they were working wrong, others were following their lead, so they had massive fines in addition to going bankrupt
