If it's actually legitimate, that's very good uptime.
How often is your pingdom set to test the site? Something seems off, as when Hostgator moved everybody to the EIG datacenter in Provo, UT (without telling anyone), the minimum downtime for anyone, as far as I am aware, was about 10 hours. That's coming from Hostgator themselves, and their own figures. Some people were down for days.
