Re: Don't worry folks...
Superhub is total rubbish, as is the packet loss at Smallheath and Manchester in the network, and the apparent loss of all packets as it leaves the VM core for Telia's cross-water links.
My SH3 craps out when certain devices join the network when there's a certain number of other devices already on the Wi-Fi. It then assumes an IP conflict on all wireless addresses, and loses the sync with the network, requiring a reboot. I haven't managed to figure out the combination required to cause the fault, and because off and on fixes it, Virgin don't regard it as a problem.
This is balanced, mostly, by the service being fairly reliable, and reasonable stable latency-wise. Although, 50m/s to Munich is a bit leggy by modern standards.
