Since voting has a different meaning on Meta, what does it mean if someone upvotes an official announcement? Further more, why does this question even have a downvote? Why is this question heavily downvoted? I'm confused.
Upvote on official announcement means I like what's being announced, usually.
Even if I don't really like it, I might still upvote since the team spent time on something, and that's something worthy.
As for downvotes, if I really dislike what's being announced I'll downvote to express this. Announcement with negative score means the community does not accept whatever is being introduced there, and it's vital feedback for the team. They might even reconsider the decision.
As for the single downvote on this question (with 197 upvotes), it's just noise; it does not mean anything. Someone might dislike SE making such an outage, or someone just downvoted random keys. We can't know, and shouldn't really waste time trying to figure this out.
