MDN Plus

I was sitting on the train yesterday, when I opened a tab with a page from MDN that was already loaded. It quickly jumped to 'cannot connect' even though I didn't refresh. I wondered why it did that, but it makes perfect sense now.

Now I use Zeal[1] to still have the documentation available offline.

There are explanations for that that aren’t as nefarious as what you’re implying.
