Internet outages on a almost daily basis

​We have been experiencing almost daily internet outages for over three months now, despite having replaced the Comcast modem and using our own SB8200. These outages can last for as little as 5 minutes or sometimes even hours, and restarting the modem does not seem to help. Whenever we contact tech support level one, they always seem to blame our equipment, and the problem often resolves itself and our ticket is closed.​

​Upon looking at our modem logs, I noticed that there are lots of T3 timeouts and some fairly high error rates. Based on my observations, I am quite certain that the issue is with the cable or something on the local telco pole causing interference. However, I am having difficulty getting through to a Comcast technician who can schedule a repair of the cable.​
