Don't waste your money buying CL's 40/20 Service
I switched to Centurylink about a year ago when they rolled out 40/20 service in my area. It had its ups and downs like any internet but I've let them slide. For the past 2 months however their service has slowed to a crawl. Where I used to get 4megabytes a second download, I'm now lucky to 700k.
Using CLs speedtest still shows 40/20 service. But any real use scenarios slow to a crawl.
Back to Comcast for me.
