I read a comment from CMDR Buur on his youtube channel
on this topic:
Important fact! - frontier have stated on numerous occasions that galnet will now only report on things actually in the game ...IF this is in fact the return of Galnet then the consequences are potentially far deeper than just some in cockpit text to read.
It's not inconceivable that the news isn't Galnet, but that a news story in game will break on thursday and be in Galnet. It used to be thursdays when the Thargoids would appear of course ...
