Actually, the FB IPO open fiasco was on Nasdaq not BATS. Nasdaq, has had way more serious issues in the last 2 or 3 years that I can recall compared to NYSE. [EDIT] The BATS issue you may have been referring to is BATS IPO when they tried to list on their own exchange. The technology failed miserably that day, so much so that they decided to pull the IPO altogether. One of the biggest fails I can think of.
