Facebook, Instagram, Whatsapp, Messenger, and Oculus (FB Services) were down yesterday. They (Facebook) changed the persistent storage (Which contained an error), which caused every client to try and correct itself by sending queries to the FB databases. A few hundred thousand requests a second per client. This cause the databases to become overwhelmed, forcing FB to shut them down and replace the change to the previous code. Then restart the database servers.
Other services have been reported to be out, like cell services to cable/ISP services.
This may have seemed to be affected but the only thing that was actually down was the fore mentioned services.
