Until I get everything sorted out, some aspects of Xbox America will remain offline to reduce load. This includes gamercard images and the site summary at the bottom of each page.
I have some planned optimizations that will also help reduce server load, but these will take a while to implement.
Sorry about all this, and hopefully we'll be back to normal—or better—soon enough.
Thanks for your patience,
Jackson
Update: The gamercard images are back up with a new caching mechanism that should temper their CPU usage.
Update 2: The site summaries at the bottom of each page are back as well. They also should be at least marginally more efficient.
