its ongoing, people in the troll box have questioned how the attacks have not been repelled due to it being behind cloud flare servers the IP's of the attacks should be made public so those responsible can be taken out, unless its some kind of quasi inside job, that has been accused of many sites when they suffer bitcoin loses or close down resulting in the loss of customer funds, also different sites will be affected differently by different users sometimes sites are accesible from different locations though I expect that trolls may be largerly behind posts that say sites are accesible when they clearly are not,
I'm trading at btc-e presently, and it looks more like a deliberate attempt to spread fud on your part, honestly. The exchange did experience two major DDOS attacks two days ago, but the site was inaccessible for around an hour in the first case and for a dozen minutes in the second. If we are talking about right now ("its ongoing"), I haven't yet seen any delays today which could be attributed to continued DDOS attacks. By the way, I just looked through the exchange chat ("troll-box"), and there are no complaints there either (folks are mostly discussing when Bitcoin is going up again)...
So what is your agenda here?
