I am having a similar problem in LA. Maps load in white. when I cycle through "try next aerial photo" option, I can see them refresh to white or show the missing message. This happens on several different computers on Linux and Mac, on both firefox and chrome.
This started the middle of last week sometime. Anyone else having issues?
UPDATE : As of Aug 24th 10am PST it started working for me
