We have occasional Comcast outages. Nothing significant.
As I said, Comcast here is running on a 35-40 year old infrastructure
with minimal upgrades. OTOH Sprint rebuilt the phone system from the
ground up about 20 years ago with fiber backbones, buried service and
fresh "last mile" flooded copper. I found out I can actually up my bit
rate by using more pairs (there are 3 pairs in the cable going to the
tombstone in the yard) and paying more but I have not felt the need.
Both Comcast and ATT have upgraded their service here. But our cable was
some of the original cable in Northern California.
