Little late, but I think I see how we have such different experiences. Assuming other comments are right, and Reddit's pulling pretty much entirely from cache, you probably just scroll longer than I do - long enough to run out of the first ~1000 (cached) posts, and hit uncached items.

You'd get timeouts, and I'd never see them - despite being West Coast (Canada) as well. Or at least, that's my best guess so far.
