Many are connecting the outage to International Women's Day (IWD), particularly the Day Without A Woman strike. Women's March organizers called for those who identify as women to not work or buy anything on IWD, March 8. This serves as a protest for equal human rights and gender parity for women.

The Women's March tweeted that the darkness showed that "Lady Liberty got the memo":

Lady Liberty got the memo. On 3/8, we strike! #DayWithoutAWoman#StatueOfLiberty (Anyone know who this amazing artist is? Pls let us know!) pic.twitter.com/AGaHvk3gOj — Women's March - Text WOMENSWAVE to 44310 (@womensmarch) March 8, 2017

The event was accidental. The National Park Service, who operates the statue, explained that the outage was unplanned. National Park Service public affairs officer Jerry Willis told USA TODAY, "The outage was most likely due to work related to an ongoing project to activate a new emergency backup generator that is part of our last remaining Hurricane Sandy recovery projects."

Hours later, the lights were back on. An official explanation will come when crew members come in on Wednesday morning.

This is a developing story.
