The controversial repeal of Obama-era net neutrality protections is officially set to take effect on Monday, despite ongoing efforts from members of Congress, state officials, tech companies and advocacy groups to save the rules.  

The Republican-led Federal Communications Commission voted along party lines in December to repeal the rules, which were intended to prevent internet providers from blocking, speeding up, or slowing down access to specific online services.  

The order required the approval of the Office of Management and Budget, which the FCC announced receiving last month. In a statement at the time, FCC chairman Ajit Pai framed the upcoming repeal as removing burdensome regulations.  

"Now, on June 11, these unnecessary and harmful internet regulations will be repealed and the bipartisan, light-touch approach that served the online world well for nearly 20 years will be restored," Pai said in a statement last month.  

An FCC spokesperson confirmed to CNN this week that the timetable is proceeding as previously announced.  

"June 11 is significant because it will be the first time in the over 15 year battle over net neutrality that the FCC will have essentially no role in preserving an open Internet and overseeing the broadband market," Gigi Sohn, a counselor to former FCC chairman Tom Wheeler and a staunch supporter of net neutrality, told CNNMoney.
