Facebook and Instagram suffered outages throughout the U.S. on Wednesday, with many unable to access their pages at all.
When asked what was causing the outages, a Facebook spokesperson only responded, “We’re aware that some people are currently having trouble accessing Facebook and Instagram. We’re working to get things back to normal as quickly as possible.”
Around 3 p.m., a spokesperson said the outage was due to a “networking issue.”
“Earlier today, a networking issue caused some people to have trouble accessing Facebook services. We quickly investigated and started restoring access within about an hour, and we have nearly fixed the issue for everyone. We’re sorry for the inconvenience.”

Facebook down was trending on Twitter Wednesday afternoon.
The social media platform also experienced a widespread outage in the U.S. on Aug. 26, which Facebook said was due to “required maintenance.”
Facebook officials have said in recent months that their platform was used in part of a Russian campaign to interfere in the 2016 U.S. presidential election. The Russian-linked ads on Facebook reached roughly 10 million people, less than half of them before the election, Facebook officials have said.
