Why I am not notified for outages

I work from home. Maintenance in the area has brought my Xfinity phone, internet and cable services down 2x for the entire day over the last 2 weeks. I don't understand why it's not possible to notify me in advance of these outages (especially since they're 'planned'). I don't think Xfinity corporate would like it if someone came in and cut their connection without notice and then said their connection would be restored sometime 'today'.
