On September 16th, 2020, pre-orders went live for the Playstation 5 and Playstation 5 Digital Edition, however almost instantly, there were major issues on a majority of websites, due to the increased traffic, including website outages and in some cases, entire webpages being taken down.
However, as soon as they went live, they also fell out of stock almost instantly, leaving some disappointed and others angry that the launch didn't go as smooth as they had hoped. Playstation acknowledged this and the shortage of pre-orders and made a tweet today, Sept. 19th, 2020 with a response to the shaky pre-order opening.
Did you manage to snag a pre-order before they went? I'm still waiting for my opportunity to get one.
