CenterFuse Broadband Feasibility Report these older products. Typically, if a customer ever wants to change speeds they must change to the latest minimum product for the market, which in Ellensburg is the 100 Mbps product. However, more often we've seen Charter unilateral increase speeds, and just a few years ago, most of the customers that 100 Mbps products today had 60 Mbps speeds. • The speed tests also show that Charter made the upgrade to DOCSIS 3.1 and is offering faster broadband speeds. Six of the customers taking the speed test claimed to be buying the 400 Mbps product. Two of these customers were reporting speeds slightly faster than 400 Mbps while the rest were getting speeds between 139 Mbps and 355 Mbps. This is perhaps the best evidence that Charter only promises "up-to" speeds and does not guarantee that customers get the speed they subscribe to—that speed is a target, not a guarantee. • Two customers say they are subscribed to a 900 Mbps product. One reported a download speed of 428 Mbps on the speed test while the other got an impressive 887 Mbps. • The most important thing we took away from the speed test is the achieved speeds are inconsistent. While there are households that reported speed tests at, or even a little above the subscribed speeds, over half of the households are getting speeds slower than the subscribed speed—some drastically slower. This indicates that there are likely local network issues in the Charter network that mean broadband quality is better in some neighborhoods. We've often seen that a cable company network doesn't perform uniformly throughout a city. This could be for a variety of reasons. There could be parts of the city with larger nodes, meaning more people share the broadband. There would be parts of the network where the coaxial cable has aged and has more problems. There are numerous wiring and electronics configurations and issues that could contribute to slower speeds. We have further evidence of inconsistent network performance from the residential interviews. A number of residents complained that broadband speeds varied throughout the day—an indicator of nodes that are getting overloaded (at the slow times). A little over 1/3 of residents said that home broadband was not good enough for doing homework or for working from home. • Interestingly, a half dozen of the businesses we interviewed told us that they don't think that people moving from Seattle would be happy with Ellensburg home broadband. We know from having done work with the city that the basic broadband speeds in Seattle are closer to 200 Mbps. Seattle also has the second highest percentage of households in apartment buildings and condominiums, and many of those buildings in Seattle have speeds faster than 200 Mbps, up to gigabit. The combination of the speed tests and the surveys would lead us to agree with the assessment that people coming to the market from Seattle will find the broadband in Ellensburg to be slow. We received upload test results from 41 Charter customers. Charter Upload Speeds 0—5 Mbps 4 6— 10 Mbps 5 11 — 15 Mbps 23 16—20 Mbps 1 21 —25 Mbps 10 Page 30
