I choose to not assume to "what/which single point of failure" this reference by Randy applies. However, we can take confidence in the fact that Google's Gmail service architecture is distributed; not to be interpreted of course, as suggesting that within the distribution, there isn't a single point of failure. Perhaps, from a network operations point of view, the point needs elaboration.
I think that Randy might be conflating single point of failure with "resilience". Google, distributed on every level as it is, is still just one operator and in this case the lemmings faithfully followed each other into the sea. We've been on an anti-resilience binge for quite some time, accelerated to warp speed by the advent of the Internet itself. There's something to be said about not having all of your police scanners, etc, etc on the internet from a resilience standpoint, but the siren call is strong for good reasons too. Mike
