There’s a war going on between Netflix and Verizon and it doesn’t appear that it’s going to slow down anytime soon.

Netflix has been trying to become more transparent to it’s customers and at the same time, they’ve been working on deals directly with broadband providers to get the optimal speed for their users. Netflix has said they would take responsibility when they had infrastructure problems that may affect a customers performance, and at the same time would point out when those problems arose from their broadband partners.

This new Netflix effort came to a head on Tuesday night when Vox Media’s Yuri Victor posted a screen shot of his Netflix screen to his Twitter account. Business Insider reported that the screen shot posed above, clearly blamed Verizon for the buffering that was going on during that particular movie.

On Thursday Verizon fired back with a cease and desist from in house council Randal Milch. In the letter Milch said:

“Netflix’s false accusations have the potential to harm the Verizon brand in the marketplace. This potential harm is broader than only the experience of a customer viewing Netflix content. The impression that Netflix is falsely giving our customers is that the Verizon network is generally “crowded” and troublesome. This could cause a customer to think that any attempted viewing of video, whether it be Hulu, YouTube, or other sites, would yield a similarly “crowded” experience, and he or she may then choose to alter or cease their use of the Verizon network.

 

In light of this, Verizon demands that Netflix immediately cease and desist from providing any such further “notices” to users of the Verizon network.”

He gave Netflix five days to comply with the request.

Netflix responded to Business Insider indicating that they would not be backing down from Verizon, or any other provider for that matter. “This is about consumers not getting what they paid for from their broadband provider. We are trying to provide more transparency, just like we do with the Netflix ISP Speed Index, and Verizon is trying to shut down that discussion…” a Netflix spokesperson told Business Insider.
