As I understand it, the SLA is mainly applicable to uptime only. There are no guarantees on upstream bandwidth and on downstream for the 330Mb product BT Wholesale only offer Best Endeavor to provide at least 70Mb at peak times.
Well if its the same as FTTP, its not a guarantee of a minimum of 70Mbps, but 40Mbps.
Ask you ISP what the guaranteed minimum speed is at peak times.
Anything lower that the guaranteed minimum and BT refer it as a fault.
Its a guaranteed minimum of 78.125Mbps to the exchange (2.5Gbps / 32) where 2.5Gbps is the bandwidth of the fibre from the splitter to the exchange, 32 being the amount of splits from the splitter to the buildings.
Now how they group you all up in the infrastructure I don't know.
TBH I have seen my mine go down to 45Mbps twice over the last 3 to 4 months I have had FTTP.
It mostly sits around 120Mbps to +200Mbps at peak times, but it depends on who else is sharing the bandwidth with.
But £300 pm is rather a lot to pay with the guarantee of a minimum of 40Mbps, I think the 40 to 80 packages have a guarantee of 20Mbps so I have been told by BT.
Please also be aware you notice the drop in speed more when you are on a faster connection.
