WINSTON-SALEM, N.C. (WGHP) -- City officials have given an update after online systems have remained disrupted for nearly three weeks in one Triad city. At the end of December, online services in Winston-Salem were impacted by a "cyber event." On Friday afternoon, they held a press conference updating the public about their progress in resolving this issue. City Manager Patrick Pate thanked the city employees for the hard work they've put into restoring the system. According to Pate, the event occurred on Dec. 24. He describes it as "an unauthorized access" by an unauthorized user, which prompted the city to take certain online services completely offline in order to prevent further access. They say they've made "a great amount of progress" in resolving the issues, and they are "still working to make sure all of our systems are completely safe" before they turn them back on. Pate reemphasized that this outage has not impacted emergency services, and planning services is still operational. An incident with PowerSchools did impact WS/FCS but is unrelated to the incident with the city. "We do not want to rush our recovery efforts." They also reiterated that they are not aware of any identity theft or fraud resulting from this incident and they thank the public for their patience. The timeline for when those systems will officially be back online is still undetermined.  A lot of the city’s work has gone offline. Pate said a lot is being done manually. Residents are also paying utility bills in person. When they do, they get an old-fashioned written receipt. Background On Thursday, Dec. 26, officials said in a conference that they were working to investigate the source of the event with state and local agencies. They were also working to confirm the full impact on city systems. Investigators do not believe any personal information was compromised, but certain city computer systems have been taken offline. There have been no disruptions to the fire department’s and police department’s abilities to respond to calls, according to officials. Winston-Salem Forsyth County Utilities customers were assured they would not experience utilities/service interruptions, and there would be no late fees or penalties charged to accounts that couldn't make payments due to the outage. The North Carolina National Guard, the North Carolina Local Government System Association Strike Team, the North Carolina Department of Emergency Management, the FBI and two divisions of the Department of Homeland Security are working to help investigate the cyber event. “All we know is that there was an abnormality that occurred within our network and because of that we initiated an investigation,” Ben Rowe said. While online payments may be disabled, in-person cash or checks can be made at the Bryce A. Stuart Municipal Building at 101 E. First St.
