Feedback: need advance notice of internet loss

Our internet has been down all day.  There have been at least 6 different Xfinity trucks parked just outside.  The workers are friendly and doing the best the can, but our day is lost.

Comcast could not have picked a worse day to do work.  I don't think Comcast appreciates the impact this has on small businesses.  It's not just one day of lost productivity.  We had important meetings with clients that have been disrupted.  Their impression will now be that our company is unreliable.  This outage will continue to cost our business into the following weeks and months.  

Please, please find a way to notify your customers in advance of scheduled maintenance.  I understand that maintenance and repair are essential, but if we are forewarned of internet outages, we can make contingency plans to continue our work.  It's unacceptable to find out that maintenance is scheduled only after we've all lost our internet connection.

Thank you
