Good :-)

Absolutely.  I despair in this country because there's a regular 'ISP A
is faster than ISP B' graph/battle...and it really makes no sense.

If you're in a geographical/single supplier situation then yes.  In the
UK it simply doesn't work like that, any area, 'any' supplier.

Our speeds are fundamentally controlled by how close to the
cabinet/exchange you are, not really ISP controlled.  There are 2
bandings on VDSL though, 80/20, 40/10.  ADSL is a bit more 'best
effort'   Incidentally VDSL is advertised as a 'fibre' service in this
country!  You can get real fibre, but really it's Fibre(rare to the
home), Cable(Virgin Media), VDSL(effectively BT), ADSL(BT&others)

:-)  No top 100 nonsense yay :-)

I *am* very interested to see up/down bufferbloat split out by
ISP/delivery technology though.  And I am very positive about the
dslreports bloat test, it's really very good and it's great to see
people making the issue of bufferbloat more measurable and more
mainstream.  Apologies if I've sounded less than appreciative.
