Facebook began experiencing issues just before noon ET Wednesday that has brought the social network and its family of applications to a virtual halt for hours.
There was initial speculation about a massive distributed denial-of-service (DDoS) attack, but that does not appear to have been the case.
A Facebook spokesperson said late Wednesday afternoon, “We’re aware that some people are currently having trouble accessing the Facebook family of apps. We’re focused on working to resolve the issue as soon as possible, but can confirm that the issue is not related to a DDoS attack.”
Facebook’s dashboard for developers was still reporting a “partial outage” as of 5 p.m. ET, saying, “We are currently experiencing issues that may cause some API (application-programming interface) requests to take longer or fail unexpectedly. We are investigating the issue and working on a resolution.”
Facebook did not respond to a request for comment on whether advertisers would be compensated for the extended downtime.
