March 24, 2018 - The Mariposa County Sheriff's office reports TDS phone lines have been restored to the majority of TDS customers. They are still working on pocket areas that have not been restored as or yet. 

If you are in a location that has not been restored and you have an emergency please use a cell phone. We have Deputies patroling those areas still affected by the downed phone service. 

We will keep you updated with any changes and timeline information as we get more details.
