This isn't much of an issue for traders That'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. 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't reporting any lost trades or trade busts yet so this isn't as bad as the BATS open at BATS:) Having said tha…

Great info, thanks! (Very minor, but "ping" usually implies ICMP Echo Requests, and ICMP doesn't have ports)

UDP and TCP include echo ports (port 7 just like ICMP) and many tools that can run in non-privileged mode actually use the UDP echo instead of ICMP.

It's very common to "ping" a service by sending a valid request and seeing if you get a valid, expected, non-error response.

Genuinely curious: What are your qualifications?

I work at the exchange...there's no off-shore sweat shop. There are no people in india running commands or coding for 90 hrs a week. Folks in multiple US cities fixed this problem, including myself. I've only read comments here previously until I saw all this speculation. Its funny people are so adamant in their theories despite no evidence besides circumstance.

I wonder if people are looking for a 'deeper' story because "shit broke, fix was prompt, PR was processional" isn't as interesting as sweat shops, foreign hackers or cover ups.

A tweet from last night: "Wonder if tomorrow is going to be bad for Wall Street.... we can only hope." (source: https://twitter.com/YourAnonNews/status/618626955433349120 ) Good call on their part. Coincidence?

I get the impression they'd heard on the wire that something might go down.

Given the blame coming out of China, it wouldn't surprise me if they tried to crash the market on opening with a flurry of sells. Looks like NYSE got a whiff of the pending trades and the NSA stepped in. All trades dropped. Crisis averted. For now...

If there's smoke there's fire. In my view, Occam's razor might indicate that coincidence is unlikely, and that the two major incidents in US on the same day China's market crash suggest it's a state sponsored cyber attack.

You state this in response to a comment linking to a good description of why, precisely, this is broken thinking. Did you even read it? Also, you've got Occam's razor around backwards, always a good way to cut yourself in public (Occam's razor resists adding more complexity to the solution without evidence)

in the real world, people have to draw on their wisdom, intuition and guts, intelligence and common sense in order to make immediate partially speculative conclusions/decisions. there’s no luxury of engaging in pointless pedantic philosophizing that the ivory tower can afford.

state sponsored cyber attack is less of a new variable than coincidence could ever be. 3 major us computer systems down on the same day chinas market crashed, not related at all, all just a coincidence, really? were the WTC attacks and pentagon attacks on 9/11 also two different "coincidences" or part of one same group of attacks?

this site is a prime example why even average iq 100 people can outthink iq 140 engineer types at some tasks by a multiple factor using intuition and common sense since the smarter people rely overly on the slower left brain analysis that can't take many variables into account quickly, making them come up with some astoundingly morbid conclusions.

Er, I didn't mean that to sound accusatory. I was questioning if that is what the poster actually meant.

I posted above....it was a complex IT problem, fixed by individuals in multiple US cities, by US citizens. No hacking attempt, no Wall Street conspiracy...computers just break, and today they broke more than normal. Btw, i'm purposely being vague since this isn't really public information.

I'm confused why it is in your interest to create a new account to post on here with a report that it's an internal issue, but then offer not even the barest technical detail when you apparently have evidence, all the while chiding others for having no evidence themselves.

Your vagueness isn't serving anyone. If you're worried about confidentiality, you would have been better off not posting at all.

The only things that gave me pause today in attributing this all to an Occam's Razor explanation are:

1) The government's careful wording about this not being an "intrusion" (which leaves open DDOS).

2) The lockstep tempering response is about what I'd expect from an industry which, almost as a matter of national if not global security, has to project a stabilizing confidence to averts irrational panics over even mundane hacking attempts.

I can believe that it is a simply an internal IT issue (apparently requiring people in multiple cities to work like crazy), but I also wouldn't be surprised to hear a completely different story emerge in the next few months as they slice the sausage of public release. It wouldn't be the first time that the initial narrative of a rogue element in the financial industry was shown to be inaccurate, and only revealed months later after an appropriate cooling off period.

IMO 'thetruther's putative view from the inside is useful even without supporting evidence. Not every assertion needs peer review, and the community doesn't always have the right to demand it. (That doesn't mean I'd make a significant decision in reliance on his unsupported comments, of course.)
