I've cleaned up the looking glass and route server pages - they had gotten kind of stale. The ping and traceroute pages still have some dead links in them - feel free to help the cleanup!
I just axed 80,000+ user accounts, most of which were spammers. If I deleted your account, I'm sorry, you'll need to re-register.
