IB has gone down several times in the past 2 trading days (Friday and Monday). Anyone who is logged onto the chat here at ET knows that it isn't just an isolated individual using a subpar connection.
Let's be honest -- they are having an issue or 2 this month but I still think that they offer decent service, excellent fills, and tthe emini price is awesome. I am still with them if this turns out to be an isolated issue.
I also believe that IB has a large chunk of the Emini volume going across their servers - I guess sometimes success creates operational issues.
