Zen New gateway? :: Zen Internet

Today my Zen connection dropped. I'm GEA migrated and had been having poor performance (typically 450Mbps speedtest.net for Zen's own server with a 900Mbps connection). Tonight I'm back up to line rate after the connection drop, albeit my latency is much worse - appears to be going via Manchester. What is interesting is that the traceroute looks a bit different to previous, the gateways are not gateways I've seen before, they don't seem to have proper DNS info, either... Is something big changing?

Disconnecting and re-connecting put me back on one of the old London gateways, with the same 1/2 speed results.

Try as I might now I can't get back on the "fast" gateway. I wonder if it was some kind of test gateway that just picked up a few connections?
