Sometimes I think we're too nice to you. Today we've teamed up with the website monitoring service Pingdom to give away 50 free accounts - normal cost, $119.40 for the year.
The service monitors up to 5 websites, checking to see whether your site is online - if it goes down, you can be notified via email or sms. The checks are pretty advanced - for instance, you can set a check to occur every 5 minutes and notify you only when the site is down twice in a row. The message can be repeated or sent just once, and your contacts can also be notified. Paul Stamatiou has a full review.
No need to comment for this one: just head to http://www.pingdom.com/mashable and sign up. We've got 50 accounts to give away, and - lucky for you - it's a Friday night and most Mashable readers aren't around.
