It says "Unlimited high priority 3:1" for Home and "Unlimited high priority 2:1" for Plus. What does that mean?
To me, it means that if throughput is 66% or 50% below line speed respectively, the service is operating as sold.
I take your point, but I also share Bob's concern that it is very unlikely Pulse8 are buying sufficient backhaul capacity to dedicate bandwidth of 1/3 (Home) or 1/2 (Plus) the sync speed of the connection. I would be asking what the 3:1 and 2:1 figures actually mean in contractual terms and in practice before basing any purchase on them.
I have never noticed any visible contention on my Zen FTTC connection (Zen backhaul), though there is no way Zen are providing me with an uncontended connection on consumer 'fibre broadband'. Zen sell '
NGA Ethernet', which is FTTC or FTTP with uncontended, SLA guaranteed bandwidth - I don't have indicative pricing, but I'm sure it's a lot more than £46.99 per month!
