If this outage was due to a security threat, and we don't know that, inconvenient as it may be, I'd rather put up with an outage, and knowing that Apple is on top of the situation, or at least working on it, than happy and blissfully, typing away, and being totally ignorant of a potential security flaw, that could wreak much more inconvenience on my life.
Security vulnerabilities are an annoying fact of life, we have to live with for now.
