The fire department found that while the vehicle was deployed in response to the Mendocino Complex Fire, data rates provided by Verizon were being throttled to speeds that made the service largely unusable. Through a series of emails, the department requested that Verizon stop throttling its data or offer a plan that didn't include usage caps -- their plan at the time instituted data throughput limitations after 25GB had been used. A Verizon accounts manager suggested a $100 plan, more than double what the department was currently paying, that would charge $8 per gigabyte after the first 20GB.

The Mendocino Complex Fire has consumed more than 400,000 acres since late July and is now the largest wildfire in California's history. "The internet has become an essential tool in providing fire and emergency response, particularly for events like large fires which require the rapid deployment and organization of thousands of personnel and hundreds of fire engines, aircraft and bulldozers," Bowden wrote in the addendum.

The department ultimately did switch to the more expensive plan. And while throttling has been a tactic used by ISPs for some time, particularly with unlimited data plans, the incident still highlights the issues with the FCC's net neutrality repeal. When classified as a Title II utility, carriers were prohibited from "unjust or unreasonable practices," and as Ars Technica notes, Santa Clara could have filed a complaint to the FCC claiming that Verizon's actions violated that specification. But those protections are now gone.

Additionally, the FCC's Open Internet Order gives consumers fewer legal recourses to combat such actions and a rule instituted in July rendered the FCC's complaint system less effective.

The lawsuit brought forward by the attorneys general was combined with a number of others brought forth by tech companies, rights groups and county governments in March.

Update 8/22/18 3:30AM: Verizon said in a statement that its policy is to "remove data speed restrictions when contacted in emergency situations" for services on so-called unlimited plans, but in this case, an employee made a mistake. A full comment is below.
