Heh, maybe freeze is the wrong term. The issue I have is that I go to submit things after I fill out all the information and then it WON'T go through to the uploaded page... :/ DA is such a busy site that I'm not surprised by that, though. Also, that may work for you, but my works are very diversified so much that I can't just keep using the same submission categories all the time (though, I probably could've just been lazy and left things the same all the time).
Furaffinity is just as active as DA, but I rarely ever have an issue uploading things there. The only problem I've had in recent history is when I go to upload something, my browser will occasionally say the site froze on me, but it immediately corrects itself and continues to the submission page, so I just ignore it. I figured that may either be because the site itself is busy, my file is somewhat big, or it's probably my adblocker conflicting with the site momentarily (which is more than likely because I know it does that sometimes on sites that have a lot of ads). In any case, it hasn't really happened lately and it never really bothered me before. I would invite you to join, but I can't vouch for content. While the site does have a mature filter (which I keep on at almost all times), some of the stuff is a little questionable... *facepaws* Who am I kidding? It's almost all the same as DeviantArt, give or take the fact that it's all FURRY stuff.
