It seems like only yesterday that I was writing about Notify Me When It's Up, a site that lets you know by email when a website comes back online. Actually, it was a few days ago, but someone has already built a fancier version of Notify Me. It's called Ding, It's Up, and it adds SMS and Twitter notification options, and tells you when a site goes either up or down. Despite my praise of Notify Me's minimal approach, I am forced to concede that Ding outdoes it.

I previously commented that it was nice that Notify Me keeps things simple, even though it could have added more features, or incorporated the functionality of Down For Everyone Just Me. I guess the creators of Ding, It's Up are basically sticking their tongues out at me, because they've done just that, and it's actually pretty neat. Just don't use it to sign up to receive updates by Twitter about when Twitter is down. You might want to use Is Twitter Down? for that.

UPDATE: No more Notify Me When It's Up! Now the URL just redirects to Ding. Thanks, Sanjay.
