Welcome to the TBB forum!
Hmm, is noise present on your line? Dial 17070 and select option 2, the line should be quiet. It has always been the case that BT Hub's tend to reboot several times a week. The only change to the SNR margin I can see is on the upstream side, this is likely to have dropped due to crosstalk, nothing to be concerned about just annoying as it can affect line rate.
Please could you post the results from http://www.dslchecker.bt.com
and use the telephone checker as this gives the most accurate result.
Hope this helps.
