How to handle a potential sudden huge traffic load tonight?
patio11: I really don't think you're likely to have scaling issues.  Your site appears to be static (if not, freeze it temporarily, since there is no dynamic content which adds customer value -- aside from the purchasing pathway, and honestly if your website gets brought down by too many people hitting that at once then you should just take your lumps like a man and then console yourself that as soon as you fix things you can retire to your own private island).It is very, very difficult to knock over a site, even on shared hosting, with just static files which are not rich media.  You'd need to have thousands of users a minute.  I am not familiar with the podcast, but I am familiar with the concept of conversion rates, and based on the expected conversion rate from someone hearing a URL to typing it in unless his podcast gets piped in over the loudspeaker at MacWorld I rather think you're unlikely to get more than four figures of visitors out of it.  You'll get through four figures in a breeze.(Candidly, I think I wouldn't be hoping to see four figures myself, but that might be natural pessimism.)
