From the article in the other Slashdot thread on this issue: https://arstechnica.com/tech-policy/2018/08/verizon-throttled-fire-departments-unlimited-data-during-calif-wildfire/
Update: In a statement to Ars three hours after this article was published, Verizon acknowledged that it shouldn't have continued throttling the fire department's data service after the department asked Verizon to lift the throttling restrictions.
"Regardless of the plan emergency responders choose, we have a practice to remove data speed restrictions when contacted in emergency situations," Verizon's statement said. "We have done that many times, including for emergency personnel responding to these tragic fires. In this situation, we should have lifted the speed restriction when our customer reached out to us. This was a customer support mistake. We are reviewing the situation and will fix any issues going forward."
Verizon also noted that the fire department purchased a data service plan that is slowed down after a data usage threshold is reached. But Verizon said it "made a mistake" in communicating with the department about the terms of the plan.
"We made a mistake in how we communicated with our customer about the terms of its plan," Verizon said. "Like all customers, fire departments choose service plans that are best for them. This customer purchased a government contract plan for a high-speed wireless data allotment at a set monthly cost. Under this plan, users get an unlimited amount of data but speeds are reduced when they exceed their allotment until the next billing cycle."
Verizon also said that the Santa Clara "situation has nothing to do with net neutrality or the current proceeding in court."
As for the myth that the fire department had a consumer plan:
Verizon specifically says: *"This customer purchased a government contract plan for a high-speed wireless data allotment at a set monthly cost."*
