Internet unstable for last few days and speeds drop by half during time

[KingClouds]

Over the past 4 days my connection has been intermittent around 6-9pm. Where my speeds drop by half especially the upload but it occasionally drops out for a couple of seconds and reconnects, resetting the box yesterday seemed to fix it for the whole day but today the issues continued to happen again. I have no clue what's going on as later into the night the issue seems to disappear.  BT were recently installing fibre in the area so maybe they knocked something?

There are too many Pre and Post RS error across all the Downstream channels.
Is there a known fault reported for your street via 0800 561 0061 ?

[KingClouds]

When I check on their website it says there's no known errors in the area but a couple of my friends in the area said they're having problems as well so I was wondering if virgin media knew if there was a problem in the area as it's been happening for a couple of days now.
