Optimization or throttling?

Yesterday, we reported that Verizon Wireless appeared to be throttling Netflix traffic, — and today, the company seems to have come clean. In a statement provided to Ars Technica and The Verge, Verizon implicitly admitted to capping the traffic, blaming the issue on a temporary video optimization test.

“We’ve been doing network testing over the past few days to optimize the performance of video applications on our network,” a Verizon Wireless spokesperson said. “The testing should be completed shortly. The customer video experience was not affected.”

This is a really weird statement, seemingly referring to something completely different from what customers actually experienced. What customers saw wasn’t optimization, but a clear cap, with tests from Netflix’s speed-test tool showing measurably lower rates than non-Netflix tests.

“If this is what Verizon means by optimization, it looks an awful lot like throttling”

While Netflix was the only service to have a speed-test tool producing measurements, it now appears that similar caps were applied to all video applications on the Verizon Wireless network.

A subsequent statement from a Verizon representative took issue with this article, calling it “dead wrong” and saying that it “makes no sense.”
