I've now been with Plusnet for 18 months, and my contract is up.
I've been signed up to their fibre offering paying approx. £35 for month including line rental.
I ran a speedtest now (on a Tuesday evening), reaching 73 mbps down and 19 mbps up, with a 32ms ping, so rather decent. I've not had any issues with them to boot. (They can be forgiven the massive outage last week that affected all their users, and the poor signal and speeds over WiFi, which aren't their fault)
I'm just wondering whether I ought to stay with them and continue receiving decent broadband, or shop around and find something better (performance or value); any thoughts please?
