Hi, guys. We had a few people call about this as well. I checked with the web team and apparantly there was some monster port sale that was hogging all the system resources for a while. Everything should be working fine now, but fyi we're planning to replace the main server pretty soon so that stuff like this isn't an issue again. I'm sure Tim will post on the blog when that happens, so keep an eye out.
Thanks for letting us know when you experience slowdowns like this - it isn't always obvious on our end so we really do appreciate how involved our community is. =)
