All feed generation and delivery has been moved to the new server. You do not need to make any adjustments to your frames, they will automatically switch to the new server over the next few hours.
The web site is still running on the old server so will continue to experience slow response until I finish moving that as well.
This should resolve several issues with sporadically missing photos, invalid RSS feeds and general wonkiness. Please let me know if your frame is still unhappy.
