We get our communication services from Centurylink, landline phone and DSL internet. We have two lines, personal and business. Monday afternoon, our DSL's both quit, while our phones still worked. Rumor has it that there was a large group of CL workers about six miles away, on the other side of town. That would be where the fiber would be coming from the bigger city. We finally got service again about 11PM Tuesday night. I assume that someone damaged a fiber optic cable that required a great deal of splicing.
It would be typical of Centurylink to not maintain any redundancy. They don't even supply enough bandwidth to handle normal traffic. We can tell when the kids get home from school closer to town, since reception slows down noticeably. So much for "rings."
