My nearest BT fibre is a few hundred metres away. BT says it can deliver 30-42 meg here, & 6-8 meg upload.Virgin is currently delivering 'up to' 30 (in practice at least 30, e.g. 33 just now), or 60 if you pay more, & promising to uprate 30 to 50 later this year. Upload is much slower than BT promises, though, only 2 meg.
Interesting that its asymmetry thing1. Perhaps some traffic shaping on the switch access ports.
And BT are reducing theirs from 0.9 mbs to 0.2 mbs. At least where I live.
Until FTTC arrived, I was getting 2Mb or so on a good day, so I sympathise with people like TimC . OTOH, I am contemplating a move to somewhere where I might not get even 2Mb. It is a major deterrent.
