Hi Brock,
We're working with site caching to improve performance and reduce load on our servers. Only anonymous users will see cached versions of pages, that's why when you log in you see the latest.
You are correct, it's not related to the outage from earlier today.
Sorry for any inconvenience. We'll be changing the expiration of the cache soon which should cut down the time between updates greatly.
Thanks for your post and please let me know what problems you're having with uploading images so that I can check it out.
