In the last few months the site has really been straining the limits of the current hosting server, which resulted in slowdowns on page loads, sometimes failures and seemed to be the cause of the occasional corrupted table. After talking with my hosting company we've been upgraded to a more power server with far more room to grow.
The upside of this is the site should be more stable and responsive, so better for everyone involved. This does increase the cost of running the site a bit, and in the past some people have asked about donating to help support the site.
