It was just seeming to be less responsive, overall -- I was wondering to myself if maybe it was a DDoS attempt underway maybe, or something like database not indexed optimally, and now with it growing it being a problem than is observed, or something.

It could easily have been my wi-fi as well -- who knows. I'm not seeing the SN performance problems today, so if you didn't change anything on your side yet then the problem was likely on my end.
