Not sure what it is but my iPad has been acting very weird in the past few weeks. It randomly goes slow sometimes and I also have to exit Safari when web pages don't load and it seems to work again after restarting it. I have had iPad's since the first one so I know how they work and the iPad 3 has starting doing this in the last few weeks. I also have restarted it and drained the iPad's battery and charged it fully, none of that really makes a difference. It just seems to glitch randomly and it seems fairly often now. It sometimes even glitches in such a way that the whole iPad freezes for a minute and the home button doesn't even do anything.
