This map shows what regions of North America and Europe were still experiencing Facebook outages at 6 p.m. ET, three hours after trouble began Monday.
People hoping to see what their "Facebook friends" were posting were greeted with "service unavailable messages" for much of Monday. The world, however, continued to spin on its axis.
Users experienced trouble accessing the social network for several hours starting at about 3 p.m. ET in the United States. Outages continued into the evening for many.

Monday's outage came four days after 2.5 hour interruption that Facebook called "the worst outage we've had in over four years." It blamed the previous on "an unfortunate handling of an error condition."
"An automated system for verifying configuration values ended up causing much more damage than it fixed," the company said in a statement last week.
Lead Stories' European bureau confirmed the outage involved that continent, as well as North America.
