As your site grows in popularity you are bound to face some downtime with your site, particularly if you end up getting dugg or slashdotted. Once your site reaches its bandwidth limit, users will start seeing error messages and may end up forgetting about your site and not coming now. There is a new service cleverly called L8ter which should help out. If you find a site that’s down, but that you’d like to come back to, simply head over to L8ter and enter the link of the site as well as your e-mail address. L8ter will then query the site until it comes back up, then inform you, via e-mail so you can go back to it and check it out. Additionally, L8ter offers a Firefox extension called Monitor with L8ter, so you can monitor a site right from your browser. Like all great things, it’s 100% free.
