January 24, 2026 My ISP is overall mediocre. No major issues besides some outages for maintenance and weather and whatnot. They usually communicate about those pretty well. However, for the same service and speed, the price slowly creeps up every time it's time to renew. I'm paying much more now than when I originally started using them, but not getting any increased value for the services.

December 24, 2025 I am pleased with my providers speed and package options, however, their pricing continues to go up and is becoming more and more unaffordable. I really wish they would get creative and offer more customized options for customers like me to save money and get the entertainment I need. Their customer service also leaves something to be desired as it's unhelpful and limited in scope.

December 19, 2025 I reveived a two year special rate of 60$ per month for Gigabit service, which I feel is an excellent deal considering at my last residence the same service was over $100. Been very happy.

December 15, 2025 My internet provider is in general pretty reliable, but serves bad IP addresses which are randomly blocked on things like Prolific sometimes.
