I received a call from my daughter, last night, during the Alabama - Clemson game asking what could be wrong with their cable service. I don't have Comcast/Xfinity except for my internet provider and this morning my internet service went down. I'm posting this using my personal Hot Spot through my cell phone.
That said people are going to experience outages with Comcast and other wired services when it gets this cold due to line breakages. Also if there is a bad connection often times it will not become evident until the extreme cold weather causes the conductors to contract and separate.
So hopefully everyone will have their internet and the outage will be more local than wide scale, affecting many more people. I hope everyone has a Happy New Year but it sure is starting out Cold and for myself, and my family, it started out with us being ill. We have been fighting a bout of the flu even though I received a flu shot earlier on. Best of luck to all and hopefully we all can get through this cold spell without any damage to pipes or other things other than some minor outages from time to time. Remember the pets and try to make sure they have a warm place to lay down and get out of the extremely cold weather.
