North Carolina is also reporting outages while Virginia is braced for impact. Despite the storm’s abating force, winds remain strong and surges are causing flooding in low lying areas.
Through recent days network observations have been used to assess the technical impact and geographic extent of Hurricane Dorian since the storm impacted the Bahamas on Sunday, revealing extensive, lasting damage to infrastructure while Dorian battered the Abacos and Grand Bahama. The Bahmian health minister reported several casualties while areas in the direct path of the storm have been rendered uninhabitable.
In 2018, NetBlocks reported on the network impact of Hurricane Florence as it tore through North Carolina and in 2017 the mapping system was deployed to map Hurricanes Harvey and Irma.

NetBlocks diffscans, which map the entire IP address space of a country in real time, show internet outages corresponding to connectivity disruptions. Purposeful internet outages generally have a distinct network pattern used by NetBlocks to determine and attribute the root cause of an outage, a process known as attribution which follows detection and classification stages.
