Heavy rain and other extreme weather conditions can affect the speed of your broadband connection. In some cases this may also cause connection problems. You should bear this in mind before reporting a broadband fault.

I knew hot weather degrades microwave links but I’m wondering how heavy rain can alter a wired systems performance. Then again I had my broadband knocked out by an upgrade and an engineer too lazy to turn off diagnostic mode before moving on to the next upgrade.
So I’m confused too.
