Unauthorized activity on internal administrative computer systems prompted Metro to limit access to those systems, resulting in station monitors not displaying arrival times, the transit agency announced Thursday.
Customers seeking to add funds to TAP cards via Metro’s website or customer service lines could experience issues, prompting Metro to advise them to do so at ticket vending machines.
Rail and bus services were unaffected. Customer and employee data have not been affected, according to Metro.
Metro said it is working to restore access following a series of security checks.
