I'm working on a solution for this, but ultimately it comes down to hosting costs. SearchYC is currently hosted on a cheap-ish virtual server whose costs come out of my pocket each month. I can't justify spending more money on this project, given my personal financial constraints.

Traffic has been steadily increasing, and quite simply, the system can't handle the load at peak usage. I am, however, working to resolve some of these issues, but it may still be awhile before you see any improvements.
