UptimeRobot – Free dashboard uptime monitoring for any websites
This can be useful if you have one or more hosting providers and need to keep stats (or be alerted) when the sites are unavailable. The service is free for up to 50 sites and a min of 5 mins periods (more than that you can upgrade to Pro with a comparison at https://uptimerobot.com/pricing), you can set an RSS feed, get e-mail alerts, have a custom public uptime page (like mine at https://status.gadgeteer.co.za/). The free account probably has more than enough for most people.
