# Best Fiber Internet Providers in Round Rock, Texas (2026)
Round Rock has grown into one of the Austin metro's most dynamic suburbs, with a population exceeding 135,000 and a booming economy driven by Dell Technologies' global headquarters and a growing cluster of tech and biotech companies along the I-35 corridor.
