It went down in South Kenner (70062) just a few minutes past midnight. I too was hoping for the long awaited speed increase but that was just wishful thinking. I had to rely on wifi tethered T-Mobile to get my fix during the outage, which ironically is sometimes faster and more stable than my fixed cable connection from Cox.
Last October I had no upload speed at all. They said it was something at the plant and it was fixed. What could have caused that? No frequency or power change was observed. I did have a few T4 and CMTS errors on my log at the time.
