Thanks for the heads up, Outdoorsman. Fiberville.com is not their
website. It's
http://tdstelecom.com. TDS is a fairly large regional telecom that bought the Union Telephone Company about 6 six years ago. Union served Alton and was in the process of installing fiber even back then. I think its legit although I suspect you are right that it's still far from covering most of the town. The website shows the Rum Point area is to be complete in 2015.
That being said, I still can't find any reviews of the service. But can it be worse and more expensive than Metrocast?
