(FOX 11) - Facebook went down on Monday for the second time in a week.
Facebook on downdetector.com, which monitors disruptions, showed major outages over parts of North America and across the world.
The outage lasted for about 45 minutes, and many users started reporting that it was back by about 12:45 p.m. PT.
Facebook also suffered a similar outage last Thursday.
#FacebookDown quickly became a trending topic on Twitter. Several users posted that Instagram and Tinder were experiencing issues as well.
Tinder uses Facebook profiles to authenticate "real people" and maintain quality control, which may have been the reason for the dating app's outage.
Regardless, it was a social media meltdown.
