Nasdaq, has had way more serious issues in the last 2 or 3 years that I can recall compared to NYSE.&lt;p&gt;[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.</text><parent_chain><item><author>chollida1</author><text>This isn&amp;#x27;t much of an issue for traders  That&amp;#x27;s a nice benefit of having 40+ trading venues in the US.  They had problems at the open as well with connectivity on one of their gateways.&lt;p&gt;Issues like this crop up all the time and most of the time they are resolved before the open.
The good news is that they aren&amp;#x27;t reporting any lost trades or trade busts yet so this isn&amp;#x27;t as bad as the BATS open at BATS:)&lt;p&gt;Having said that, they&amp;#x27;ve announced that they will cancel all open orders, that is a huge deal, I can&amp;#x27;t remember the last time they did that.&lt;p&gt;To put that into perspective, cancelling all open orders would be the Silicon Valley equivalent of Ebay loosing all bids on their current auctions.&lt;p&gt;NYSE has always been considered second rate in their IT compared to the NASDAQ and BATS and this won&amp;#x27;t do much for their reputation.&lt;p&gt;&lt;i&gt;&lt;/i&gt;EDIT&lt;i&gt;&lt;/i&gt; meant BATS not FB, thanks!&lt;p&gt;One other point to keep in mind when throwing around hacking conspiracies.  The exchanges aren&amp;#x27;t running on public networks.  You can&amp;#x27;t DDOS them or hack directly into the matching engines.  Though I&amp;#x27;m sure you can break in via some other NYSE owned network and make your way to the matching engine somehow.&lt;p&gt;To hook into the exchange you either go through a blessed intermediary like GS or you plug directly in via colocation.  You just can&amp;#x27;t keep pinging the NYSE on port 80 to bring it down.</text></item></parent_chain></comment><story><title>NYSE/NYSE MKT has temporarily suspended trading in all symbols</title><url>https://www.nyse.com/market-status/history</url></story>

It&amp;#x27;s much better than letting them stick around and then execute with unexpected behavior. It looks like NYSE learned from what happened related the FB opening (just as you alluded to), and what happened with Knight around the same time. Playing it safe can be a smart move, even in the stock market.</text><parent_chain><item><author>chollida1</author><text>This isn&amp;#x27;t much of an issue for traders  That&amp;#x27;s a nice benefit of having 40+ trading venues in the US.
