Ding It's Up is a free service that alerts you via text (SMS), twitter or email when a website goes down or when it comes back up. We will never send you a text/email unless it is to inform you about a website you requested information for - you can unsubscribe at any time. If you would like to talk to us just email us at firstname.lastname@example.org - Thanks!
When deciding on a server you want to make sure you have enough system resources to handle the load of your website. We'd recommend at least 2 Gigs worth of memory cards and a fast processor. If you are concerned about uptime, it may be a good idea to use uptime monitors.
