My home internet connection is provided by TalkTalk. I have their medium fibre package. If I had to rate the service out of 10, I’d give it 5 (and even then only just). The consistency isn’t great, the DNS is flakey and TalkTalk keep getting hacked (see here, here and here) meaning I deal with an increasing number of spam calls. Good points are that the service is relatively cheap, and works fine most of the time.
