I have CenturyLink 1Gbps in Colorado Springs. Not sure what you mean about not upgrading their infrastructure. The price is $75 fixed forever as long as I always pay my bill on time.
Centurylink in Fort Collins offer 'up to 40 mbits' but it's rarely that fast and costs about $48 a month. Plus router rental. That's what we mean about them not upgrading infrastructure. They had their chance, and now the city will compete with them.
They used to quote their speeds in ATM frame rates, not in IP speed, and ATM has a lot of overhead. 15%? I wonder if their 40mbps is still quoting frame rates rather than actual IP throughput. Not sure, because 40mbps isn't enough for my home use, so I haven't even talked to them.
Where 40mbps isn't sufficient you mean? A family of 4 with a hell of a lot of video streaming being the primary one, but also not wanting my own Youtube videos to take 3-4 hours to upload 20 minutes. :-)
Personally, I hate those "fixed price forever" Internet offers. The price of Internet continues to trend down, I think of these plans as "We guarantee we will be overcharging you in 2-3 years" plans. :-)
Could you please talk more about how why you consider the facts you've cited "$75 fixed forever" relevant to the "not upgrading their infrastructure" discussion?
it's also important to note that these companies are known for lying. I've had five separate CenturyLink employees lie to me over the phone in the past week and a half so I don't really even think their word something you can rely on.
