Didn't catch that announcement and it could have been a factor for others, but couldn't have been the issue when I attempted to play as it was during one of Jason's live streams. I tried to jump on mobile while he was looking for someone to play using the "early access" version.
So, it could not have been a downtime, if others are online playing. Possibly a glitch of some sort. I wondered if the new release interacting with the mobile platform was creating some kind of glitch with the new "early access"... it may have been ironed out as it has returned since then. But something funky was happening.
