Unfortunately working from home cannot make domestic broadband any more reliable or resilient: it's still delivered by one of about thirty million standard Openreach circuits, and at any point in time a percentage of those inevitably have problems.
You'll need to log the issue with Sky and go through their standard troubleshooting.
