@iatn boringly the explanation is nothing like so interesting simply its coming into winter and we have had some really bad weather which always cause issues with copper phone lines. Full fibre is far more relisble as the simple fact that high frequency electrical signals running down decades old copper wires can be disruoted by water and high winds is inescapable. Expanding capacity at the exhange is not an issue.
The fact that Sky's service checker often gives a stupidly optimistic answer is down to the way Sky identifies a line is down which lags by an hour or often longer. So it is as good as a chocolate teapot to telling you why your line has just lost connection however it can tell you if Sky are aware of an issue affecting the lines in your area.
Intermittent connections are typically due to bad lines conditions but unffortunately as the whole copper network is due to be de-commissioned at some point Openreach are increasingly unwilling to spend money patching it up so getting them to replace the joint which is causing an issue isnt always possible.
