It seems like my problems earlier today were symptomatic of something a fair bit larger. Several major sites (ebay.com, about.com, livejournal.com, 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 ebay.com and/or about.com and post in the comments!) Even MORE strange, the websites themselves are accessible! I can pull up ebay.com 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.
