Cellular and Internet services were down after Friday night’s storm (http://wapo.st/KSPWn8 ), as reports of slow or intermittent service came in from Virginia, Maryland and the District.

A Verizon representative confirmed that there had been “voice outage and no signal” in parts of Virginia, including Herndon, Manassas and Woodbridge. In a statement, Verizon said that as commercial power was being restored, some services would come back and that they were working to fix service.

AT&T officials said there were issues with dropped calls in Virgina but did not have more information.

Local radio station WTOP reported that AT&T technicians were “mobilized and currently working to resolve the issues,” according to a company release.

A T-Mobile spokesperson said that mobile generators were set up at cell sites without power overnight Friday and early Saturday morning. By Saturday evening, nearly two-thirds of T-Mobile cell sites in the Washington area were operational.

Sprint did not have any information about outages.

Some landline phones were reportedly not working in Reston, while internet connection remained unaffected.
