An accompanying tweet indicates that the experimental balloon-based internet distribution system has 100,000 customers in the storm-ravaged island. AT&T and T-Mobile users are able to connect to the balloons, which are circulating around the region by machine-taught navigation.
The FCC granted Project Loon an experimental license on the Band 8 frequencies for LTE. The service will be around for however long the need remains and get further refinement of navigation patterns to target smaller areas.
