While it's certainly possible (likely?) that it's "just" a technical issue, the article talks about this:

> The mass outage comes just hours after CBS’s 60 Minutes aired a much-anticipated interview with Frances Haugen, the Facebook whistleblower who recently leaked a number of internal Facebook investigations showing the company knew its products were causing mass harm, and that it prioritized profits over taking bolder steps to curtail abuse on its platform — including disinformation and hate speech.

> We don’t know how or why the outages persist at Facebook and its other properties, but the changes had to have come from inside the company, as Facebook manages those records internally. Whether the changes were made maliciously or by accident is anyone’s guess at this point.

I think we can't completely rule out the possible connection to this. Again, likely isn't, but answering the question how one might come to the conclusion.
