As if the repeal of net neutrality weren’t unpopular enough, Verizon’s decision to slow down the cellular connection used by firefighters as they battled a recent wildfire appears to have taken the longstanding fight to yet another level. In the wake of Verizon’s latest face-plant, a coalition of more than 1,000 firefighters, EMTs, paramedics, and other first responders have signed an open letter urging Congress to restore meaningful net neutrality rules. “We routinely place ourselves in dangerous situations to assist others and save lives,” the first responders said. “But since the Federal Communications Commission repealed net neutrality, the communication services we rely on to do our jobs are no longer meaningfully protected from being arbitrarily slowed, blocked, or otherwise degraded by internet service providers.”

The department said the 50 Mbps “unlimited” Verizon data connection it purchased was routinely being slowed to speeds as low as 30 Kbps. “Throttling affects our ability to provide real-time updates and coordination of resources at these large fires,” said Adam Cosner of the California Professional Firefighters in a Reddit AMA. “When we were throttled we lost our IP phones, our ability to check the state database of resources, our ability to update the status of resources within the incident, and all of our situational tools.” While net neutrality rules allow for “reasonable network management” by cellular carriers during times of congestion, the firefighters say their connection was routinely throttled for no reason. When Santa Clara Fire Department complained to Verizon, Verizon’s first instinct wasn’t to fix the problem, but to upsell the department to a far more expensive plan. After the story gained nationwide attention, Verizon admitted that the throttling of first responders was in violation of Verizon’s own policies, but in a statement to Motherboard denied that the fracas had anything to do with net neutrality. In a report for NBC News, former FCC lawyer Gigi Sohn stated the FCC’s elimination of net neutrality rules also eliminated the first responders’ ability to complain to the FCC. If the rules had still been intact, the department could have complained that Verizon was unreasonably interfering with its ability to use broadband under the “general conduct rule,” Sohn noted.
