Well, I know they're still alive and well, anyway, as I've been conversing with them over the past few weeks regarding things in the upcoming issue. So I imagine it's just a hosting problem or something that shouldn't last very long.
Ping!Zine is alive and well. Katrina really threw them off-course though! Hence, the reason there has not been an issue published in quite some time. They are hard at work on the October issue, and I believe it is in the final stages.
