Hi All,

We've been under DDoS all day (since about 5 am PDT). We managed to mitigate it pretty well but it never went away, has varied in intensity, and still impacts site performance. Whoever is doing the DDoS is probably doing it to manipulate price and of course they are going to try to cause trouble right when the market starts to move and is most ripe for manipulation. Also, heavy trade action puts more load on our resources and, when we're also under DDoS, could contribute to the site being less responsive.

So, yes, there's a correlation right now between site access/performance and heavy price action. I'm not sure why people think this correlation is reason to question the DDoS explanation because the explanation fits perfectly well. Sure, there are other explanations that fit too, and ultimately we can't prove to you that it's in fact DDoS and not something else. I understand why people are inclined to distrust exchanges though in light of history.

We are investigating to see if we can find a connection between the DDoS and trading on our site and will take appropriate action if we can identify someone, but it may be very hard to do so.

As I already mentioned, we will also further enhance our DDoS protection. But DDoS protection only comes in degrees, so making it stronger can't rule out the possibility of being impacted by a larger attack.
