Not by me it isn't. I would go beresk.
For example, I was expecting to watch the Wimbledon Men's Final without even the slightest chance of any glitch, and all was indeed good, absolutely no slowdown here at Weaver Towers. I would have been Mr. Angry otherwise. Zen did actually know Xmas was coming, it's quite predictable, to be fair.
I have used Zen, they were good in my experience (over BT). Fast ADSL link.
Hear good things about IdNet.
