It probably is regional, yes, because I simply can't believe every time I write a comment like this here or somewhere else I'm told reddit works fine. It gets on my nerves every single time I visit at night. (Western Europe)
I almost never have a problem on desktop, but using iOS safari (and the mobile reddit site), I often see the error page. I think it's a view/rendering issue, and ends up being displayed rather than a loading modal, but I could be wrong.
