Gab seems to be having some kind of issues right now. Either it's down again (he's doing a lot of work on the sight, he's taken on literally millions of new users in a very short amount of time b/c of big censorship obviously) or they've taken it down. I'm getting a different error than I've been getting when he's just working on it the last few days. I don't know about the tech end, just know it's down.
