By the most likely road route I live 3km from the exchange (2.74 SamKnows). For some unknown reason BT, after a repair to the cable near my house, set my target SNRM to 3. As a result I got extremely high sync ~9000 kb/s in the day, but at night would drop by about 800+ kb/s. No worry that!
By chance I needed to disconnect and reboot yesterday to accommodate Erin Dors's housewifely desires.
Fluke!? The connection has held as here

Another funny is that until a week or so attenuation was 47dB: now 46dB. Bandwidth used may also have increased slightly
Could it be that FTTC run out or other changes have unexpected effects on normal ADSL2/2+ lines?
