It's not possible to give a simple answer to that question.

99% would be fine for me, as long as I am not relying on OpenID during
the 3 days that my OP is down. And even if I were, 99% would still be
fine if those 3 days' downtime were spread over the year, as some 72
1-hour outages, about every 5 days. On the other hand, given an outage
comprising a solid 3-day block starting at 9:00am on a Monday, by
Tuesday morning I would have abandoned that OP forever.

The question keeps coming up: is OpenID just for commenting on blogs, or
is it supposed to be useful for more important purposes? I'm not given
to commenting on blogs. But if that's all it's meant for, then my remark
(above) is unreasonable - you're really asking how much inconvenience
I'm prepared to put up with, rather than how serious a 3-day outage
would be.
