SAN ANTONIO (KTSA News) — It appears people were putting down their phones during Monday’s Facebook and Instagram outage.

AT&T is reporting that their mobile network experienced a pretty significant drop in usage while the social media platforms were experiencing difficulties.

In San Antonio, the mobile network saw about a 7.4% drop in traffic during the 6-hour period that coincided with the disruption.

Facebook says the outage was caused by “Configuration changes on the backbone routers that coordinate network traffic between our data centers.”
