The latest Customer Satisfaction Index is out from ACSI, which measures the public satisfaction of a wide range of U.S. industries and institutions. The survey this year continued to show that the public has a poor opinion of ISPs. As a group, ISPs had an average ACSI annual rating of 68. The only industry with a lower rating is gas stations at 65. Subscription TV had an average rating of 69, and the U.S. Post Office had a rating of 70.
But there is some interesting good news for some ISPs. Companies serving customers with fiber rated higher with the public than other ISPs, including cable companies using coaxial networks. Consider the following table that shows the 2023 ranking for fiber and non-fiber ISPs.
For companies that offer both fiber and another technology, customers served by fiber liked an ISP more than non-fiber customers. CenturyLink has the biggest difference in satisfaction (78 for fiber and 62 for non-fiber). Frontier also has a dramatic difference (74 fiber and 61 non-fiber). The only cable company ranked for both technologies also has a sizeable difference, and Comcast has a ranking of 73 for its fiber network versus 68 for the coaxial network.
Customer satisfaction involves many other factors than just technology, but the differences for the companies that offer multiple technologies have to be mostly related to fiber. However, there are other factors in play. For example, it seems likely that CenturyLink and Frontier provide better customer service and faster repairs for fiber customers than for DSL customers.
Cable companies have to be noticing this giant difference as part of any consideration of how to upgrade their networks. The big cable companies are all at the beginning of the upgrades to improve upload speeds on coaxial networks, and they must be hoping that customers like them more after the upgrades. But there is a chance that the public has come to think of fiber as a superior technology and will not rank a coaxial system as highly even after speed increases. There is still a noticeable difference in latency and jitter between cable and fiber networks, and customers who see both in action believe fiber is better.
There is still a noticeable range of ISP rankings within each list. Non-fiber customers rate T-Mobile and AT&T the highest and rank Altice and Frontier DSL as the worst ISPs. It’s interesting to see Charter near the bottom of the rankings.
Fiber customers clearly rate AT&T as the best and Comcast Fiber as the lowest. Fiber technical performance should be consistent regardless of the ISP, so the difference in rankings between fiber providers has to be related to customer service and the other non-technical aspects of being an ISP.
