You can blame the ever so unreliable ISP Nac Net,  we use them in our office which cut out as well.<p>"
Good Afternoon,<p>At approx 12:10pm, we lost communications with some of our equipment in our Newark, NJ location.  Upon investigation, it was discovered that equipment located in the cross connect area had lost power.  Customers may have noticed degraded internet service for about 2-5 minutes while routers propagated through alternative providers.  As of 12:23pm, power has been restored in the Newark, NJ site.  We are still investigating the cause of the problem."
