Well, one mostly-sussed-out mystery solved. Bit.ly links weren't working from my company's network, and it turns out that the company has blocked it because the service was so widely used in phishing attacks.
Of course goo.gl and t.co and other shorterner services all seem to be functioning fine, but presumably phishers will be moving on to those sooner or later.
It's a bit annoying, since bit.ly is used in a lot of Twitter links, including my own and some other folk I follow regularly. This is why we can't have nice (or convenient) things.
Not the first time these kind of services have been targeted for security reasons: http://www.targetmarketingmag.com/article/bitly-googl-blacklisted-spamhaus-owly-listed-safe/1
Interesting. I use bit.ly for most of my links. I wonder if this explains why many of my posts using those links see less traffic than posts without the links.
I doubt my company's security folk are unique in taking this sort of action. Which sucks, because I like bit.ly.
(I'm not a big believer in URL shorteners, simply because they server as a single point of failure for bitrot, but there are some places, like Twitter, or even G+ sometimes, where they are highly valuable.)
Nah. StupidEvilBastard.com is blocked by my company. The reason is generic.
+Al Hunt Mine, too. "Violence." Damn, Les, and his rabble-rousing, war-mongering, violence-invoking ways.
