Facebook (FB), Instagram and WhatsApp all suffered outages midday Monday, according to public statements from the three Facebook services.
Facebook states “We’re aware that some people are having trouble accessing our apps and products,” Facebook said on Twitter. “We’re working to get things back to normal as quickly as possible, and we apologize for any inconvenience.”
Thousands of reports of outages was logged by the outage tracking site Down Detector on Monday. Facebook’s site was down for an hour; Instagram and WhatsApp were available but could not view new content or send messages.
While the cause of the outage was not immediately clear, multiple security experts pointed to a Domain Name System (DNS) problem as the likely culprit. Around 1 pm ET, Cisco’s internet analysis division ThousandEyes reported that its tests indicate the outage may have been caused by DNS issues.
A spokesperson for the company did not immediately respond to a request for comment from the HDEdge.
