100% is unachievable, especially at Google scale. Your car or coffee shop or whatever also fails 0.0x% of the time. Heck the energy net in western countries doesn't reach 99.999% uptime and I would call it very dependable.
I'd say the biggest problem it the non-existent support. It's fine if 0.01% fails, as long as there is human troubleshooting or help available if necessary.
