Sorry about the unplanned downtime last night. The traffic on the site continues to rise, and the log files for the website filled up one of the hard drives a lot faster than I had been expecting. This caused the site to be down for a little while, but it was very simple to bring it back up. We have taken precautions to prevent this from happening in the future.
Again, sorry for the downtime. As the site continues to grow, there will be growing pains, but I will try to plan further ahead and announce when we will have to schedule downtime to make upgrades.
