I'd suspect some error - either something oily or otherwise wrong with the surfaces, or the joint was clamped too hard and glue-starved.

Hi CarpenterSFO,
Thanks for responding. I understand what you're saying. It's highly possible that's what happened with that guy's granite.

Do they make a special glue for exterior use?

Thanks,
I'm not aware of it if they do. Epoxy will degrade under UV, but I'd be surprised if it could get that far into a joint. In some other client I might worry about water getting in and some freeze/thaw cycle breaking the joint open. Most slab also sell materials and equipment for people who are going to fabricate counters themselves. Give a call to the folks who sold you the counters.

On a whim, I looked up the polyester stone adhesives. Some of them specifically are limited to indoor uses. The reasons to use polyester are that it doesn't yellow, and that it's less expensive than the epoxies - that's probably a priority for the Chinese companies shipping pre-fabbed countertops. So it could be an issue. Give your local countertop shop a call.
