They are aware of it and supposedly working on a fix.
Getting annoying, but one or two weeks out of the year for the service I get from them isn't too bad. It's made me think of switching, but I have WAY too many photos there lol.
I haven't had any trouble actually uploading images, but the images are definitely loading slow once on the site. Plus, like I mentioned in the other thread, I'm getting some artifacts in my images lately.
