During Netflix money fight, Cogent’s other big customers suffered too
When Netflix and its transit providers fought with cable companies and telcos over who should have to pay for network upgrades, it’s no secret that innocent bystanders were harmed. Companies that sent data over networks that were congested because of money disputes got poorer performance, despite having no direct role in the fight.
Now Cogent -- an IP transit provider whose paths into the networks of Comcast, Time Warner Cable, Verizon, and AT&T -- reveals it deployed a Quality of Service (QoS) system that de-prioritized traffic from wholesale customers so that traffic from retail customers would get through without dropping packets. Wholesale customers are the ones delivering large-scale services over the Internet. Netflix is the largest but Cogent has other, unnamed wholesale customers who suffered because of the Netflix money disputes. When Cogent had to drop packets because of congestion in its connections to ISPs, the packets of wholesale customers were dropped before those of retail customers. Retail customers are smaller businesses whose use of the Internet would more closely resemble a typical consumer than a giant Web company.
