Verizon FiOS, AT&T U-verse trail Frontier and CenturyLink on Netflix's June speed index

Verizon (NYSE: VZ) may have moved to resolve network congestion issues that impact the quality of experience for its FiOS users that access Netflix's (NASDAQ: NFLX) service, but the service provider instead dropped two places in Netflix's monthly speed index.   

FiOS dropped two spots to twelfth place on the online video provider's June ISP Index, with an average streaming speed of 1.58 Mbps. Similar to the May ranking, Verizon's DSL was again dead last, sixteenth, with an average speed of .91 Mbps, down from the 1.05 Mbps it reported in June.  

Following an earlier agreement it made in April, Verizon last week tried to dispel what it says are myths that it is deliberately throttling Netflix traffic.

It did acknowledge Netflix's network did suffer from congestion "at the interconnection link to the edge of our network (the border router) used by the transit providers chosen by Netflix to deliver video traffic to Verizon's networks."

AT&T (NYSE: T) U-verse did not fare too well either, maintaining its thirteenth spot on the index with an average streaming speed of 1.5 Mbps. However, its DSL speeds slightly beat out Verizon with speeds of 1.15 Mbps.

DSL providers Frontier, Windstream and CenturyLink (NYSE: CTL) may have seen a slight shift in their rankings, but they all beat out both AT&T and Verizon. Frontier took ninth spot with an average streaming speed of 1.9 Mbps, while Windstream and CenturyLink took tenth and eleventh place with average streaming speeds of 1.8 and 1.7 Mbps, respectively.  

Cable operators continue to lead the speed pack. Cablevision's Optimum once again took the top spot with 3.1 Mbps, up slightly from 3.01 Mbps in June. Cox maintained its second spot ranking while Suddenlink slightly edged past Charter in the third spot with an average speed of 2.86 Mbps.

"Among the major ISPs, Cablevision, Cox and Suddenlink continue to lead the index and show steady improvements over the last three months," wrote Anne Marie Squeo, a member of the Netflix communications team, in a blog post.

By contrast, Canadian service providers Bell Aliant and Bell Canada, which both offer fiber to the home (FTTH) service, took the No. 1 and No. 2 spots with average speeds of 3.23 and 3.13 Mbps, respectively. Like the U.S.-based telcos, Bell Aliant and Bell Canada's DSL service reported slower speeds of 2.68 and 1.96 Mbps.
