ADSL systems will retrain to a lower rate as line conditions (SNR)
change for the worse. The attentuation characteristics of a given pair
will change of time due to a number of factor, including but not
certainly limited to physical wear, moisture invasion, localized source
of interference, sunspot activity etc.

Are dsl plants subject to localized environmental conditions? Absolutely.
