<tip type="Site Up/Downtime monitor">

http://www.internetseer.com offers a free service which checks the
availability of your site once an hour.

At the end of the week they send a tabulated report:

Day Mon Tue Wed Thu Fri Sat Sun WeeklyTotal

Connect time * 0.28 0.35 0.38 0.17 0.14 0.15 0.18 0.24

If your site ever goes down they also immediately send you an alert:

Error Alert
Your Web site is not responding
URL: http://www.georgedillon.com
Time: Mon Apr 15 08:14:15 EDT 2002, EST
Error Type: 403 Forbidden

Obviously these emails are trying to sell you other services, but I have not
had any spam through the email address I gave them, so the ads they contain
are a small price to pay for such an essential early warning system.
