Is it Friday already? Or is this not a troll email? Its hard to tell. 

If its not a troll: Put up some smokeping boxes. Graph it for a few nights. Gather details. Send us those. That is far more interesting/(damning?)

If its a troll: *grabs popcorn and gets comfortable* . we've not had a good "zomg the pipes, they are teh fullz, woe is Netflix" (and the obligatory cgn/v6/software vs hardware router sub thread divergences). 

Very nicely struck balance sir!
