On the Monday two weeks ago, I found that my account was switched to HK server from US server and I had not requested the server change. I contacted IB CS. The first IB CSR told me that my account had been in HK server and had not changed for over a year. I was shocked because I have been an IB client for almost four years and I was pretty sure that my account had been in US server. Then I contacted IB again. The 2nd CSR told me that truth. IB moved all Chinese residents' accounts to HK server without notifications. I really need my account stayed in US server because of a lot of reasons. I told him to change my account back to US server over the next weekend and please ask me in advanced if there is such kind of important change on my account. Last week, my account was moved back to US server successfully. And I thought it was over. But it was not. I just found that my account was switched to HK server again. Damn, it is gonna cost me another $500+ more in slippage and the possible damage caused by the server reset between 3PM and 4PM EST. There was one time that the reset lasted 33min, from 3:30PM to 4:03PM EST. Incredible, isn't it. IB, what happened to you?
