There was a massive outage yesterday that affected all Facebook applications around the world.

This brought about a fresh attention to the embattled social networking leader all over the world and affected many of its users.

The outage affected users for at least 12 hours in most areas of the world, with the biggest impact in North America and Europe, according to the tracking website downdetector.com.

After acknowledging the problem Wednesday, Facebook remained silent on the issue for nearly 24 hours before issuing an explanation and apology around 1630 GMT Thursday.

In tweet, Facebook apologised to its users for the inconveniences caused.

Yesterday, as a result of a server configuration change, many people had trouble accessing our apps and services. We’ve now resolved the issues and our systems are recovering. We’re very sorry for the inconvenience and appreciate everyone’s patience 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.
