Generally it's OK but when it's bad, it's very bad and it happens too often.
I've been a little impressed (just a little) since covid lockdown started.
My virgin connection has been better than it was when there wasn't a crisis - might be Google and such limiting HD video and what not, but still far fewer down times - just one hour in the last week or so.
As long as I don't expect to stream video in the evening, but I'm not a heavy multimedia user anyway.
