I've had FTTC from IDNet for a couple of months now. They regraded me to 80/20 a while back and things were going well. This was a typical Speedtest.net result:
For what it's worth the speed is lower than I got in actual downloads but it was consistent so I accepted it as a useful result for monitoring purposes. I'm glad I did.
Last Tuesday something changed. The latency dropped a lot (actually to a more reasonable value). What was less welcome was a corresponding drop in throughput:
Also noticeable is that instead of being a steady speed the speed is highly variable. Eratic even. Before the change I downloaded the Win8 RC at 6.9MB/s. After the change it's struggling to hit 3MB/s.
A BT Speedtest produces:
"Download speedachieved during the test was - 30.17 Mbps
For your connection, the acceptable range of speedsis 12 Mbps-76.76 Mbps .
Additional Information:
IP Profile for your line is - 76.76 Mbps
2. Upstream Test: -provides background information.
Upload Speed

0 Mbps 20 Mbps
Max Achievable Speed
Upload speed achieved during the test was - 7.01Mbps
Additional Information:
Upstream Rate IP profile on your line is - 20 Mbps "
I've reported it to IDNet but their initial response is that they don't know if they can do anything because I'm above 12Mb/s. I know quite a bit about how broadband works in the UK so I understand that it's reliant on BTw but surely something is wrong here? Surely I don't have to live with 30Mb/s throughput with a 76.7Mb/s profile?
The exchange is Brackley although I believe that we are actually getting FTTC from Banbury.
