Facebook users in the U.S. faced a nightmare with the social network.

Per reports, Facebook in the U.S. was hit by a massive outage as a majority of the users complained that they were having a hard time logging into the social network Web site.

The recent outage seemed sporadic. While some users were able to access the page, others were not so lucky. The Twitter began flowing in with user comments that Facebook wasn't working for them. Per a report by The Next Web, users from Texas to New York complained of intermittent access, although many users were not affected by the outage.

"The site has been offline for many in the US this evening - including Texas, New York and others - for around an hour and a half, although others in certain parts of the country are able to access the social network as normal. Overseas users appear to have remained unaffected," TNW reported.

Although the Web site went down for many people, mobile notifications seemed to be working, as did the mobile site m.facebook.com. However, the problem didn't seem to be contained in the U.S. only, as many users from other countries (UK and Argentina) also complained that the site was down, via Reddit.

However, it seems like the problem is over at the moment as a Facebook spokesperson has commented on the sudden unknown outage.

"Earlier today we experienced a DNS issue that briefly prevented people who typed 'facebook.com' into their browsers from reaching the site. People who accessed the site using a mobile app, typed 'www.facebook.com' into their browsers, or used a bookmark or a search engine to navigate to the site were not affected. We resolved the issue quickly, and the fix should be fully propagated now. We apologize for any inconvenience," the spokesperson stated.

When the outage hit the country, it was unclear as to why this was happening. Web site monitoring service downrightnow.com reported Facebook's status as "Likely Service Disruption" that started around 7AM Pacific Standard Time, and at the time of this writing the site suggested that it has had intermittent access for the last three hours.

The last time Facebook has such a major outage was back in December when the social network suffered a DNS (Domain Name System) issue that caused some people temporarily being unable to access the Facebook page.
