You mean that Free's ipv6 is not implemented correctly?
The only ISP not putting out v6 widely is SFR, and thankfully they've gone bankrupt and we will be rid of this scourge.
The connection is solid, though - thus my lack of enthusiasm.
One of the huge holdups for v6 deployment was the absorbtion of the then DOCSIS2-based Numericable, which required a huge migration to DOCSIS3 to even support it, as well as integration of the whole network backhaul that came with it.
The reputation _was_ justified at some point far back but they turned the ship around a long time ago and is now entirely an unjustified meme.
These past years it's been SFR (via RED) who was keeping the prices competitive, so I can't wait to see the remaining three vultures collude to raise the prices back up again /s.
> People just get pissy because Free refuses to pay for peering with Google for e.g. Youtube, and it feels slower, even more on v6.
Well when one's paying for a heavily marketed "the fastest around" 1Gbps+ connection or something, and it indeed negotiates the link at that, but one can't play a 720p video over that tube because backhaul routing sucks, one has a right to be annoyed.
