Foothill Addresses — Strong 5G Performance

Homes at higher elevations have clean line-of-sight to multiple 5G towers in the SGV below — many foothill Duarte addresses see speeds of 200 to 300+ Mbps which is higher than typical. Spectrum cable performance on foothill streets can vary by lot — older infrastructure on some streets produces inconsistent speeds. For Duarte foothill addresses T-Mobile is often a strong choice.

Yes meaningfully. EarthLink uses AT&T's underlying fiber infrastructure but operates as a separate provider with its own privacy policy that does not sell or share browsing data with advertisers — while the major telecoms have historically monetized customer browsing data. For City of Hope researchers physicians and clinical staff whose work involves browsing sensitive medical and research topics this distinction matters.
