The past week or two I've seen themes just disappear on some of my iGoogle pages. The issue i've been having is occurring around 11 pm CST or shortly there after and any tab that has a new non-Google theme on it just disappears. All I see is the Classic Google theme being displayed instead of the new theme that I selected weeks ago. This has happened at least 3 times so far all around the same time period. What's happening here??

We're working hard to facebook your prefered i-stuff.
Be patient, we'll be back soon: much more social, very mobile and with lots of new features!

I've had the theme stay, but the top banner image not load on multiple occassions, I believe around the same timeframe. Could it just be too much load on the servers hosting the new themes?

11:25 CST here and my new themes are gone again. :(

Well, at least this time it's not just me.
