Sadly, it is. For example, at my previous apartment there was a badly waterproofed joint somewhere between me and the nearest street cabinet, so for months I frequently lost ADSL synch... and when it came back, I got new IPv6 prefix. After a heavy rainstorm, this would happen many times a day.

Yes, OK, there was a copper cable fault and it took <unmentionable company> many months to fix it. OK, maybe the ISP shouldn't regenerate a prefix every time. But that's real life and I suspect I am one of millions.
