The site was down for about 16 hours over the past 2 days. The problem was identified as a systematic attack on our site from professional hackers, I suppose. Someone seems to really like us out there! Hopefully the problems are behind us now. I apologize for any inconvenience this may have caused.
We have and are taking further steps to minimize future disruptions. The podcast files are now hosted separately from the main site, so if the site goes down, you should hopefully still be able to access the files themselves. We will be looking at other ways to improve our infrastructure in the near future.
