Exceedingly long loading times

Mine wouldn't load at all for several hours earlier today. When I tried a few minutes ago it was slow. I also noticed the game seemed unstable, like it was going to kick me out (which it usually does after a few seconds). I haven't bothered visiting others because it will definitely kick me out.

I'm using an iPhone 4 with a strong wifi connection. Going to try my Kindle Fire in a bit.
