Facebook has brief outage; woe, lamentation ensue

The social media giant went dark for many users Wednesday afternoon, though it was back for most within about 20 minutes.

"Earlier today we encountered an error while making an infrastructure configuration change that briefly made it difficult for people to access Facebook. We immediately discovered the issue and fixed it, and everyone should now be able to connect," a spokesman said in a statement.

The status page for Facebook developers did not show any anomalies, though the data appeared to have been last updated prior to the outage.

After roughly 20 minutes the site was back up for most people. The site also suffered notable outages in early August and mid-June .
