With the previous router iirc, it got a D or an F. no clue about actual 
number. With the openwrt+bufferbloat fix it gets an A.

Maybe your pt 2 contained info on the ISP side of the problem, but it 
was pretty dense :) a) is it a problem (i can't imagine it not being 
one) and b) are they doing anything about it?

I've figured out that out here in the boonies that our provider -- The 
Volcano Telephone Company -- has a pedestal relatively close to us that 
terminates pots, ATM and backhauls the entire thing by fiber to the CO. 
A side thing I figured out is that they used leftover copper pairs for 
to power it which works great when battery backup is needed from the CO.

What that Implies is that there is a router or something akin to it that 
has packet buffering. I assume bufferbloat is L2/L3 agnostic so even my 
little green pedestal in the forest is possibly a source of 
bufferbloat.  Is there any way on my consumer end to check for that? Or 
does the DSLreport speed test already take that into account somehow? My 
provider actually has a speed test which terminates at the CO which is 
probably more accurate, but don't think it has the specific bufferbloat 
test. It's on the fritz right now so i can't check.

Yes, that looks familiar. I was pretty surprised that it wasn't enabled 
by default.

Any reason why? I mean, is this in any way contentious?
