The Amber Alert website was shut down over the weekend after officials in the Obama Administration decided to close it as part of the partial US government shutdown.
The site is used to aggregate state alerts about missing or abducted children.
Officials told various media outlets in Washington that although the site was not functioning, the actual Amber Alert system was working.
It's unclear why the site was chosen to be shut down, while other sites, such as letsmove.gov, a healthy lifestyle initiative from First Lady Michelle Obama was not affected.
Only 17 percent of the government is actually shut down by the lack of funding, a study from the White House Office of Management and Budgets recently found.
The Amber Alert site was brought back online sometime on Monday after being down all weekend.
The AMBER Alert Program was named in honor of 9-year-old Amber Hagerman who was abducted while riding her bicycle in Arlington, Texas, and was later found murdered.
The program is used in all 50 states, the District of Columbia, Puerto Rico and the U.S. Virgin Islands.
