For those of you that didn't receive this info from your broker, here is the official complete explanation: This is a Message From: GLOBEX Control Center Effect Date: Fri May 2, 2003 03:37 pm CST Notice Number: System Update #18 Message: TO: All GLOBEX(R) Users CAUSE: Due to a hardware failure of a major component in the network infrastructure that resulted in the inability of a number of customers to place or verify orders, CME halted GLOBEX trading at 10:40 a.m. CT on Thursday, May 1, 2003. Participants were notified at 10:30 of the pending halt. RESPONSE: Switch-over to the back-up was partially successful, but because of other events related to the initial hardware problem, the system could not be fully restored. CME technicians investigated the issue and worked aggressively to isolate and remove the faulty hardware component. All day and session open orders (i.e., everything except "good-till-cancelled" or GTC orders) were cancelled. Once the malfunctioning component was taken offline and all related systems components were recovered and tested, CME announced that the market would reopen at 2:15 p.m. with a one-half hour pre-open. Between 2:05 p.m. and 2:10 p.m., a select number of firms and customers reported that they could not receive acknowledgement of their orders. As a result of this issue occurring so close to the end of the trading day, CME deferred plans to reopen the market. CME staff continued recovery efforts, repeating steps to cancel new orders that were submitted during the pre- opening period. CME then notified market users that GLOBEX would instead open at its regular time of 3:45 p.m. for the trade date of May 2, 2003. GLOBEX equity markets opened as scheduled at 3:45 p.m. C.T. with the exception of the E-mini S&P 500(R), which opened at 6:15 p.m. Interest rate and foreign exchange products opened at their regularly scheduled time of 4:30 p.m., with the exception of the Mexican peso, which opened at 5 p.m., the Canadian dollar, which opened at 6 p.m. and Swiss franc, which opened at 7:04 p.m. The openings of these products were delayed because some orders had not been successfully cancelled, requiring further corrective action. RESOLUTION: All GLOBEX markets were open and trading by 7:04 p.m. for a trade date of May 2. CME is working internally and with vendors to ensure that a similar series of events not impact GLOBEX trading in the future. If you have any questions, please call the GCC at 312-456-2391 option 2.
