I just checked my latest Libsyn Stats and downloads are through the roof. I am getting reports that sites like Dawn and Drew are down, servers have melted all over the podcasting sphere. Thus far this site which is hosted on a GoDaddy server has kept up and we have seen over 300,000 individual hits to this site alone today.
I know that at least 6500 people on iTunes have downloaded the newest show so this is significant traffic. Be patient with the downloads as servers are getting hammered worldwide.
