Silly automated email
Now that your service has now been active for 14 days, we thought we'd let you know the speed as it stands today, by way of comparison.
Estimated line speed: 17Mbps
Current line speed: 78Mbps
You can keep a track of your line speed through our website:
The 17Mbps is the ADSL2+ rating for my line, which I have never taken up (went straight to Fibre plusnet from LLU TalkTalk).
Anyway, a bit of a nonsense really, but a weird little glitch.
