Facebook says it solved a problem that left some users in the United States unable to post photos or respond to messages on Facebook or Instagram during part of the Thanksgiving holiday on Thursday.
In an update just after 3 p.m. ET, the company said the problem is completely resolved. “We’ve returned 100% for everyone,” a Facebook spokesman told CNN Business.
The company said Thursday afternoon that it had identified “a problem in one of our core software systems.” Facebook said it “caused many people to have problems accessing the family of Facebook applications,” and had begun to restore access.
There were thousands of complaints about the fall of both social networks starting at 10:30 a.m. ET, according to the Down Detector tracking site.
It seems that some parts of Instagram were affected, including the slow update of the news and problems loading images. The interruption on Instagram caused complaints on Twitter.
The two services are prone to frequent cuts, but Thursday is especially problematic because people love to share their Christmas holidays.
In July, Facebook, Instagram and WhatsApp were inactive for almost a day. The prolonged interruption probably annoyed advertisers who spend large amounts of money to reach potential customers on Facebook platforms. The company’s flagship social network has more than 2.3 billion users, and Instagram has more than one billion.
