If it’s state actors and cyber warfare, which I think is fair to suspect, we’re probably way under the radar. We’re not quite critical infrastructure just yet. :)
For the lols attacks could happen anywhere, but this is not that.

That said, there has been problems of people scraping random fediverse servers and causing a lot of traffic, in turn sending a huge bill to the owner of the instance.
