Good news, Atlassian is technically an Australian company.
they host theirs services/data in Tasmania?
I don't think it is. I liked a simpler world we lived without having to worry or look where a company was from.
But since this administration has started to threaten allies and keeps this nonsensical trade balance and tariffs argument (which never accounts for the very bulk of what US really exports: IT and financial services which are never included in the trade balance nonsense) you need to answer in some way.
And with tensions rising staying on US services is becoming a strategic risk.
5-eyes, a bit tricky... but yeah anything that isnt a direct data pipeline to US gov and 3-letter agencies is a massive longterm win, in security and economy
