To date having switched from Be to infinity, dns servers work better, websites load faster, pings are lower, speed is 4 times higher for me, and 80mb should be available to me pretty soon on top of that.
Be WERE great, but have been steadily downhill for the past 18-24 months. DNS servers becoming a bit of a joke, more frequent disconnections and after my Netgear died I got a new Be router.... lol, to call it a router is generous, 3 later and they wouldn't stay connected, evenings being disconnected 20-30 times.
THey are doing this "upgrade" to their network which likely needed doing some time ago, but refusing to invest early enough to keep everything running smoothly and well, rather upgrading when forced to but to late. Shame really, well BT for 18 months now, will see what Be are doing in 18 months.
Their DNS servers have been terrible for a couple of years now, i have been using the google free DNS since then
