On the upside, the USPS was relatively quick to confirm that the outage wasn't actually caused by a cadre of networking ne'er-do-wells (or anything more objectively sinister). That's especially good news for some 800,000 Postal Service employees whose sensitive personal information was exposed by hackers last November - the last thing they need is more potential aggravation. Security analysts were quick to attribute the attack to the Chinese government, but officials were loathe to speak to tell Washington Post about who might've really been behind it. Still. Between that and the uptick we've seen in cyberattacks over the past few months, it's just a little heartening to see that the USPS's infrastructure headaches are least its own fault this time.
