You honestly can't make this up. My performance took a dirt dive tonight back to about half line rate, I rebooted the router and it wouldn't connect up over PPPoE, and neither would a laptop. Called Zen, after a while on hold they reset something, and it went back to working (albeit still slow).
Did a bit of gateway hopping, and couldn't seem to get on the gateways I was expecting to see... Log in to Zen portal, and sure enough, I've just been migrated BACK to the GEA service from BTW.... A new unrequested migration order has appeared in my account.
Unbelievable.
