Xbox Live and Windows Azure suffering from extended outages
Several Microsoft online services are suffering from problems this evening, with both Xbox Live and the Windows Azure cloud service in the midst of extended outages. According to Microsoft's status page, Xbox Live users may have issues accessing data and saved games in the cloud. SmartGlass is also affected, along with the Xbox Live Karaoke and ESPN apps. The problem has been ongoing for several hours and appears to be getting worse, with the company recently adding Xbox Live functionality for Halo 4 to the list of affected services. In an update posted at 9:03PM ET, Microsoft states that "We are still working as fast as we can to fix the issue."
The problem may be related to another service interruption, this one affecting the company's Windows Azure cloud platform. At the time of this writing, 52 different services are currently listed as either offline or suffering from degraded performance. Microsoft explains that Azure's storage service is currently down worldwide "due to an expired certificate." The company goes on to say that it is "validating the recovery options before implementing them," and will keep users appraised with further updates. It's not specifically stated that the Azure outage is responsible for the Xbox Live problems, but given that both revolve around storage issues the timing is certainly suspect.

Could an Internet Blackout Happen In Your Country?
How hard is it to disconnect a country from the Internet, really?
That's the number one question we've received about our analysis of the Egyptian and Syrian Internet blackouts, and it's a reasonable question. If the Internet is so famously resilient, designed to survive wars and calamities, how can it fail so abruptly and completely at the national level?
The key to the Internet's survival is the Internet's decentralization - and it's not uniform across the world. In some countries, international access to data and telecommunications services is heavily regulated. There may be only one or two companies who hold official licenses to carry voice and Internet traffic to and from the outside world, and they are required by law to mediate access for everyone else.

Why It Takes So Long to Fix a Power Outage
A storm this weekend knocked out power to millions of buildings in the mid-Atlantic region. About 443,000 lost electricity in the Washington, DC area, and over 200,000 outages occurred in southern New Jersey. The utilities that serve those two markets, Pepco and Atlantic City Electric—say it might take until midnight on Friday, July 6, before everyone gets back online. July 6th? Are you kidding? Why does it take so long?
