Spokesmen for the MBTA and the company that runs its commuter rail services say an erroneous alert that warned commuters that service "was delayed until further notice" appears to be the result of a "technical issue."

The T sent a notice out minutes later Wednesday morning telling commuters to disregard the alert.

Mac Daniel, a spokesman for Keolis Commuter Services, at first said the false alert that went out at about 5:30 a.m. was ‘‘possibly a hack,” but later said that appeared unlikely.

Daniel says the false alert applied to commuter rail lines out of South Station, which are running at about 62 percent of a normal weekday schedule as the system continues recover from a series of snowstorms that crippled the Boston area’s public transit system.
