That's it for today - the ASX has just thrown in the towel and officially halted trading for the rest of the session, ending a day marred by glitches.
ASX Ltd said in a statement there will be no closing price auction that normally takes place at the end of the trading day. The stock-exchange operator said it will advise the process for determining closing prices, remaining session states and status of orders.
We're struggling to recall if this has ever happened before.
The ASX had already delayed the normal 10am local sharemarket opening until 11.30am due to technical problems, but even then traders were complaining about big delays. Shortly after 2pm the bourse operator suspended trade for a second and what's turned out to be the final time.
"I've never seen anything quite like this before," said Peak Asset Management executive director Niv Dagan. "It's frustrating because they said they'd fixed it. We'd hope the ASX sorts things out by tomorrow to allow traders to exit positions before the Fed meeting. You've got traders and fund managers looking to change their portfolios before that, and unfortunately, they can't do that."
