Phone support did some kind of a test, said he thought the signal was not 100%, since at that time we still had phone. They've been doing a lot of construction outside, but the cable wire is not buried, so I don't know?? However, it spontaneously "fixed" itself at 1 am, so by the time the tech got here everything was fine. He checked the outside line and said everything was okay.
Cisco Modem "online light" was flashing green, now all lights are back to normal. This is also a new modem, replaced that 4 days ago. On the second call, different tech replace splitter. Third call, everything was fine was fine by the time he got there.
Haven't been there since yesterday 1pm so I don't know what's happened since.
