Now would be an excellent time to ask people who use gmail for business critical operation how well that SLA and telephone support work in practice.

I know for example companies that use email for handling customer orders at their stores. I can just imagine the loss if the system was down for hours a few days before Christmas, or worse, actually lost the data.

They have telephone support, but the agents aren't empowered to do very much of anything.

I am not going to try it. I just restored data from a backup email server these emails get duplicated to.

Yeah, to be fair I've never had to test it.
