With fairly cheap ddos services you can "just" order you can knock most servers offline anyway. Internet reachability is rarely safety-critical, and if it is, that's probably a huge design flaw somewhere because there's tons of reasons outside of your control that can make the internet not work for either the server or clients.

Is all of this inconvenient and (potentially) a serious problem? Sure. But not "zomg criminals have credit card records / can spoof random domains / read private data / etc. etc." type serious.
