I wouldn't think so either. And, in California no less. You would expect these types of servers to be offshore where they could be easily hidden. Apparently they've done a pretty good job of hiding them here in California for the past few years.
I would imagine there are quite a few people scrambling right now to set up operations elsewhere. While there may be a slight break in email spam, it won't be long before another resource fills the void. That is how I understand the system to work. ;)
