For the past month or so I've been having daily disconnections reoccuring at similar times of the day. The most disruptive and consistent occurs sometime between 4:05-4:10pm, the internet connection (wired, phoneline internet) will drop for 30 seconds or so, then drop again 10 minutes later. This has also happened at other points, all with the same pattern of short loss, 10 minutes and then another loss.
This same pattern has occured while using two different routers and I've talked to others in the area having similar issues, so it appears to be problems further down the line causing it.
