Simple one-purpose site Ding It’s Up sends you an email (or text/twitter message) when a site you specify comes back online.

Pretty useful stuff, but not content to let something remain simple I decided to make a bookmarklet so that when I’m on a site that’s down, I can just hit the link in my bookmarks bar and get an email when it comes back.

To use this, either drag the link below, or right click and select “Bookmark this link”. You’ll then need to change the bookmark properties to replace ‘YOUREMAILADDRESS’ with your email address.

Let me know when it’s back
