Ok. I've reloaded that 9to5mac website numerous times on iOS 7.1 and my iPad Air with 128gb is still fine. I didn't have to reset to factory defaults or do anything special.
This means that the iPad hardware is in the clear and is clearly not at fault. The problem is iOS in its networking stack or safari. I suspect its iOS and what Safari tries to use though as safari core code should be the same across the Apple product range with slight differences only exposed by iOS and it's focus around the touch experience.
For those who are crashing in the URL to 9to5mac, I agree that this shouldn't be accepted as norm. That site doesn't crash android, windows phone 8, Mac OS X safari, windows internet explorer, Firefox, chrome, etc, etc. To say that these people are deliberately looking for broken sites to break iOS is a sign of accepting Apple and it's flaws blindly. We have to be upfront about an issue and help each other acknowledge a problem when there is one and to see if we can help Apple find root cause rather than accept that it is ok. It simply isn't. Especially when people spend hard earned cash to buy a device built for browsing and interacting with social media channels.
I think disabling JavaScript goes a long way in helping mitigate some of the issues but there could still be some "flakiness" in how Apple is coding iOS and/or Safari or it's ability to manage configuration and trace corruption caused by other apps. In any event, if Apple iOS provides developers with a way to mess up iOS, it is still an Apple issue to resolve because Apple exposed the methods allowing for that mess to occur.
