I agree on that point, and it's history with Finland is quite...terse. It's been a duchy inside Czarist Russia, a buffer zone between it and Sweden (when both were kingdoms), it's had civil unrest fomented by the USSR, etc.
It's a relationship fraught with bad blood, but strategically it's second tier compared with CIS states, the Middle East, or the Baltic states.
At this stage I'm more curious as to whether (if Russia was actually DDoSing instead of just a poorly configured webhead with extra traffic due to 'timeliness' of the initiative) it makes sense to draw more negative attention to oneself, as Putin has, by doubling down on taking jabs at everyone he shares a border with...and if he's starting to see that himself, or if he's only observing through a very paranoid, myopic lens that he simply can't get out of his own policy rut long enough to not totally collapse the Russian state, and him with it.
