Considering CF are a much much newer network and technology I really don’t get all the outages they experience
I mean, that there itself is probably the cause. Virgin are using long-established infrastructure, plus DOCSIS is an old tech, they probably hired all the experienced staff from NTL when they took it over etc.
CityFibre is running a new and fast expanding infrastructure that’s going to have more hiccups than an old and established one using much older and established technology.
