As of 5 minutes ago, PbNation has moved to a new IP address (126.96.36.199). Our ISP is moving us to a new load balancer which means I've had to change the IP address for PbNation.com.
What does this mean to you? Well, it should be transparent, but if you run into problems accessing the site, you can browse via http://new.pbnation.com
(which I'll leave up for the next week or so) or try flushing the DNS cache on your computer.
On OS X 10.5: Open Terminal, and type "lookupd -flushcache"
On OS X 10.6: Open Terminal, and type "dscacheutil -flushcache"
On Windows: Start -> Run, and type "ipconfig /flushdns"
Sorry for the inconvenience, hopefully this will have little impact on your browsing experience.
