A fiber optic cable was accidentally cut, shutting down Virginia's online voter registration system on the final day to register.
The cable was inadvertently cut during a Chesterfield County roadside utilities project.
The Virginia Department of Elections said in a statement on Twitter that the fiber optic cable was accidentally severed and no foul play is suspected.
Technicians are working to repair the cut cable, but there is no end to the conspiracy theories online.
Many skeptics believe the cable was cut intentionally to interrupt online voter registration on the last day in Virginia.
Voting advocates said the accident couldn't have come at a worst time. Some voters wait until the last day to register, sometimes after being reminded by the news media or social media.
Virginia Gov. Ralph Northam is in support of extending the deadline one more day, but he said only the courts have the ability to extend the deadline.
