Friday's comic was located here: http://art.penny-arcade.com/photos/770509271_mUGL4-L.jpg
The most recent comic posted today is located here: http://penny-arcade.smugmug.com/photos/770836278_VG7Cr-L.jpg
The issue here is that smugmug is labled as 'Web Filtering Category: Media Sharing' by BlueCoat, which is what my work uses to filter what we can and cannot access while at work. So, I can view your website and any old comics, but the newest comic only appears as a red x. D:
Why the change in hosting?
