How do I diagnose when and why a website is down?
I consider myself to be fairly tech savvy, but I have a problem that is very strange: I can't access the Twitter website from my computer. No matter whether I try to view twitter.com or a user's profile, my browser just spins and eventually delivers the message
The connection has timed out
My Tweetdeck desktop application also stalls and fails to connect. My Twitter app on my iPhone connects perfectly, even when on the same wireless network as my laptop.
How can I debug/fix this problem?
