Facebook down: 2 data points UPDATE

 

Data point 1:  See chart for scope of Facebook outage.

Data point 2:  Facebook employees not able to badge their way into their own building.  This points to internal systems being down.

UPDATE:  Doug Madory, director of internet analysis at the network monitoring company Kentik, said someone at Facebook caused an update to be made to the company’s BGP records, which resulted in the company’s system taking away the map telling the world’s computers how to find its various online properties.    (Speculation follows:  Malicious or accidental internal mayhem?)
