I suppose we all know the standard from the telco world for the longest time has been the classic five 9s - 99.999% level. OTOH, the Internet's availability to end users has always been pretty much a "best effort" commitment built on top of that telco standard - from an end user perspective at least. Wouldn't we naturally want to see OpenID availability operate at a level of say 99% to
99.99%? This is where redundancy is obviously important as well.<br><br>Also, while OpenID may have been meant originally for blog commenting, if it now can serve as a "good," (meaning instrumental) central building block for much more utilization than that, then the degree of OpenID availability in the fabric of the Internet's identity infrastructure will serve as an unavoidable governor on its potential value to end users, to websites, and to all sorts of organizations large and small. No?
