Looks like they're doing more than basic maintenance, all the servers are down (community market and actual online gameplay servers). A little warning would've been nice, lots of dropped games

Confirmed, working now

Same here, haven't been able to access it as of yet. Maybe it won't go live until the 20th?

Not true. PS5 users and XBox users have been able to download it before now. From https://account.theshow.com/techtest/info:
"Will I be able to download the Tech Test before the servers open?
Yes. The Tech Test will be available to download before the servers go live."
Since other platforms (and some PS4 users) have been able to do so, this is an issue on SDS' side that needs to be resolved. Before the servers are up in 9min

Not to be pedantic, but that linked thread states:
"This thread is only to provide help on how to download the Tech Test on PlayStation."
Not for questions about the forums. But yes, there are also multiple threads about the forum. Either way:

"A private forum will be available for those who were selected to participate. The private forum will open shortly before the test servers go live on 2/22."

I didn't see a notification warning at all, but when I went to my inbox this morning, the invite was there. So if you didn't see it on PS4/PS5, try reboot your box and check your Notifications/Inbox.

I saw a link on the tech test page saying "Join the Discussion". But the page there says that the forums won't open until just before 10am PST, when the servers go live. Check https://account.theshow.com/techtest/info
