Mainstream Fiber Networks is proud to announce that we have built over 120 miles of fiber optic cable infrastructure through Harrison County. This includes both our mainline project as well as several adjoining neighborhoods that had high participation in our interest survey. Because of this, we are now able to provide our services to approximately 10,000 households in the area, and that number will only continue to grow over the upcoming years. The neighborhoods we are currently serving are listed at the bottom of this page.
Mainstream Fiber is the only 100% fiber optic to the home internet service provider in Harrison County. We do not stop at the pole or take other half measures; we make sure to provide fiber directly to the home, business, or wherever you need it most, Our service starts at 50 mbps download speed and extends all the way up to 1 Gbps. Beyond that, our service is not, and never will be, subject to data caps or throttling.
If you’re interested in getting reliable high speed fiber internet, we may already be available in your neighborhood. Call us at (844) 752 – 6736, check online at msfiber.net, or visit our regional office in Corydon at 2370 Landmark Way to see if you can get signed up today.
If we are not already in your area, please take our survey at msfiber.servicezones.net/harrison and encourage your neighbors to do the same. We rely on demand to expand our network, so the most proactive neighborhoods will be connected first. Not only that, but taking the survey ensures that you will be notified the moment construction of our network begins in your area. Join the many who have already completed this step as we continue to grow and expand throughout Harrison County.
