During a conference call today that I was hosting, and utilizing internet WebEx hosting, I suddenly lost phone and internet services. No warning, just a sudden failed line and service. I tried to call back in, but the phone was dead. I looked outside and saw an Xfinity Service Van. I walked out and asked what had happened. He said it was a planned outage that would only take 30-mins or so. I asked if it had been communicated to area customers and he didn't think so due to the proximity of the area impacted. My question to him was "Why not?". If I had known a short outage was planned, I could have rescheduled my meeting. This is very poor customer service!
