Same here, Yesterday before going to sleep, the site was so fucking low it was really hard to use. Today I can't log in anymore. It"s weird that when you try to login you get a 404 error message but the URL is
https://kraken.com/500. with a message telling how great and trusted they are bla bla bla. Someone mentioned a DDOS, but I don't buy this story. Look at their twitter accounts. No news, they never posted something since this incident started..
@memberx it works only a few seconds every hour
