It seems that maybe their anti-ddos service; cloudfare works by preventing anyone from logging on. This was a prevalent problem 2 weeks ago being shut out randomly for hours at a time. For about a week until last night it seemed to work as expected but now twice in 12 hours I am out of the market until who knows when. Cloudfare may be preventing DDOS attacks but they are also preventing people from legitimately using the site. A trading site cannot function if people can't trade.
