I've just been changed over from VDSL to Fibre Max.
According to Vodafone's Website:
"In really good conditions, we expect you'll get max download speeds of up to 700-900 Mbps and upload speeds of up to 400-450 Mbps."
According to Ookla speedtest, tested at several different times of day I get from 90-420Mbps down, and pretty consistently 475 up.
I wanted reasonable upload speeds, so I'm pretty happy with that, as I'm getting better than advertised, and it's the main reason I went to a faster fibre plan because the cheaper ones were only offering 20 up, and I was getting 28Mbps up according to Ookla on VDSL.
The Fibre Max is in some ways a bit of overkill, however lack of moderate speed plans with decent upload speeds limited my options. Asymetric plans seem to be a hangover from the old asymetric ADSL, and pre-cloud internet, however with increasing use of a variety of cloud services by consumers it would make sense to offer symmetric plans as standard.
Unfortunately Vodafone doesn't offer any symmetrical plans eg 100/100 or 200/200 and the 200/20 is still the same upload as 100/20.
A 200/200 or maybe even 100/100 would have been perfectly adequate, but the only way to get upload as good or better than what I had on VDSL was to go to the Fibre Max plan.
What performance are other people getting on Fibre Max?
