The Internet is Down

It seems like my problems earlier today were symptomatic of something a fair bit larger. Several major sites (,,, perhaps others) are inaccessible by both ping and tracert. Equally strange, the tracerts all seem to fail at completely different locations. And I have tried originating them both from my development machine in Canada, and a remote server in California. (PS: If you know what I’m talking about, try your own tracert to and/or and post in the comments!) Even MORE strange, the websites themselves are accessible! I can pull up in a browser, or grab it with wget. But I can’t ping it?! Before today I would’ve said that’s impossible. If you’re an internet guru (or just know what’s up here), please enlighten me.
