Well - the client I have most difficulties with at the moment in an Exchange / Leased Line situation is at 20 x 5 downtime minutes for the last year, which given the usual level of reliability I expect is pretty horrendous - and despite the credit crunch we're making efforts / investment to make it more reliable.
That's still 8.3 minutes a month, which would make it amply within Google's SLA's. Most of the leased lines are 99.9% SLA as well for example, but certainly as far as I'm concerned if any of my Leased Line operators actually delivered 99.9% uptime I'd desert them in a heartbeat for an inadequate service.
And remember the above example isn't a 'mission-critical' application, which we would pour more resources on in any case.
I suppose the three nines 'in the cloud' (shoot me if you must) will end up kind of be like the badge we all expect, but something which doesn't actually have any correlation to the actual reliability of the product - you know, like those regulatory badges on PSU's we never bother to find out what they're exactly about.
