There could many reasons, like a weak internet connection for example. But the first thing I would do is to reboot your iPad. To reboot, hold the power and home button for at least 10 seconds (hold past the swipe to shut down if it appears) until the APple Logo appears, then let go of both buttons and your iPad will reboot. Then try to open the site and see if you can open it.
