Uptimeinspector is primarily a website and server monitoring service but they also handle such things as search engine rank monitoring and DNS black list checking for mail servers. The website monitor will check the availability and performance of any given URL and you can choose to have your site monitored at intervals beginning at once a minute and up to once per hour.
Obviously, the more frequency you choose, the more expensive the service will cost but when you consider that it costs $6 per month to have your site checked every five minutes, price is probably not going to be a major issue. With all Uptimeinspector offerings you can choose how to be alerted in the event that your site or server goes down including being alerted by phone, ICQ, AIM, MSN, Email or RSS feeds.
