…your internet connection happens to get cut off.
I experienced that today (luckily was taking day off – so it didn’t really matter). There were several hours long maintenance work being done by our internet service provider, and I couldn’t access anywhere. My game development relies heavily on the Ogre3D online documentation, Wiki and their community forums.
If the Internet connection is not available, then the docs won’t be available.
What are you doing to deal with this kind of issue?
