The system seems to have reduced your sync-time noise margin to 3dB from the default 6dB, as it has decided it is stable. That has added considerably to your downstream connection speed.
It's worth noting, if you don't already know, that connecting during daylight hours is likely to give you a higher speed (ongoing) than connecting at other times.
We can also see from those stats that you this time it is on ADSL2+, whereas earlier it was ADSL2. The attenuation has risen by a few dB, as it often does on that change. It is possible, (not certain), that if we can find a way of getting you back down to ADSL2 that another few hundred kbps will appear.
Don't go messing a lot though, or it might put you back to a 6dB margin and lose the big gain.
