A trading simulator company is trying to rebuild its online trading website following the shutdown of its website on Wednesday.

Sierra Trading’s website, Sierra Trading Simulator, was taken offline for several hours by a server outage in the US.

The company said it was “working to restore the website” on Thursday morning.

The US Department of Homeland Security (DHS) said on Thursday that it had shut down Sierra Trading company’s website due to a network outage.

It did not say how many customers were affected.

Sierra is one of the largest online trading platforms in the world.

It has over 200,000 customers in the United States and more than 100,000 globally.

The shutdown came as a shock to the company.

“We were on the verge of launching the website and I could feel the excitement and excitement in people’s eyes, and we just knew that it was not going to happen,” Sierra Trading president and CEO John Wollman told the BBC.

The website was supposed to open as early as Thursday morning and would allow customers to buy and sell shares of companies such as Sierra Mining, as well as hedge funds, credit cards and bitcoin.

The Sierra Trading website was taken down due to the shutdown.

It was not immediately clear how many people were affected by the shutdown or what the company planned to do.

Sierra Mining said it had no immediate comment.

Once we have a clearer picture of the cause of this outage, we will provide an update.”
