You know, major sites used to go down all the time. It was the hallmark of the Wild West internet. We simply accepted it, took a break, and focused on our own 9s (uptime). Twitter went down so often that their outage page image became ubiquitously known even outside twitter as "the fail whale."
This one is less about decentralization of internet services as much as it is about WHY THE EFF DOES YOUR WORD PROCESSOR REQUIRE INTERNET???
