That's the trouble with clever tools.. when you use them too often you find things that you would not LIke. That happen for no reason you can find, effortlessly. (Could this explain tea baggers?)
And as you say, the graphs do not indicate anything strange at that time.
Oddly too, today: Atlanta GA gets a 0 (100% packet loss.) Is Box messing with his Box-net again?
(He also seems to be hammering Canada; that's bloody-well un(ex-) Patriotic innit?
And I get 12.12/0.73 --> Atlanta just now,ergo; slow but not-quite-0
This stuff is just ephemeral and should not be pondered by amateurs. :-/
(Yes, had noticed the expectedly-convenient tools array within OS X; on one occasion it handily pointed out the source of some many UDP attempts (stealth mode) attempting to flummox firewall -- somewhere in China -- as well as noise on Comcast. Just fills up f/wall logs is all.)
Thanks for the reminders (sans deserved sarcastic 2 X 4 to head.)
Leaves with tail between legs..
