Recently Ive started getting terrible latency at peak time of the day and also at random other times - as per the below trend - is this likely to be a Cityfibre or Vodafone issue (before I try and tackle vodafone CS)?
I've made a similar post to this, which seems to happen at peak times. They do anything to pinpoint it to your house. I've had many arguments with them recently because I'm trying to explain that it's outside of my house deep within the network and they don't get it at all. Make sure to also keep a complaint timeline, as my complaint got closed despite it not being fixed.
