"The Healey-Driscoll Administration is closely monitoring the CrowdStrike technology outage and working to mitigate any impacts on Massachusetts," a spokesperson for Gov. Maura Healey said Friday morning as what one expert called "the largest IT outage in history" came into better light.
The governor's office said the Department of Transportation was the only Executive Branch agency that uses CrowdStrike services significantly, though some independent agencies, municipalities and the Trial Court also rely on CrowdStrike to some extent.

The tech outage did not affect Massachusetts' 911 emergency reporting system though public safety officials were monitoring that function closely, Healey's office said. But in New Hampshire, 911 services were affected.
At the Massachusetts RMV, all customer service center appointments scheduled for Friday morning were canceled "as many workstations at centers are not operational," and the statewide vehicle inspection system was not available, the Registry said. Road test appointments were still taking place as planned Friday.
Because some Massachusetts hospitals were affected by the outage and many chose to cancel elective procedures Friday, the Department of Public Health was working with hospitals to put procedures in place for any downtime so they can continue to provide care, the governor's office said.
DPH activated its Department Operations Center in Marlborough to take any calls from health care providers across the state.
The Massachusetts Port Authority said Friday morning that its systems were not affected by the CrowdStrike issue. But some airlines that fly in and out of Logan International Airport were experiencing computer issues that led to delays, and Massport urged travelers to check with their airline to find out whether their travel might be impacted.
The Massachusetts judiciary experienced "technical issues in some areas of operation" on Friday morning, a spokeswoman said.
"About half of staff workstations were impacted by the outage and are in the process of being restored," court spokeswoman Jennifer Donahue said in a statement. "In addition, the Trial Court’s transcript recording system, For The Record (FTR) is not operating in a number of courthouses, which is causing a delay in some court sessions. The Trial Court’s case management system and public portals, MassCourts.org, are fully functional."
The outage did not affect the Massachusetts Legislature, where lawmakers were holding double-barreled Friday formal sessions to get an overdue fiscal year 2025 budget to the governor's desk.
"We are not aware of any disruptions to IT infrastructure, and continue to monitor the situation closely as it unfolds," House and Senate spokespeople said in a joint statement to the State House News Service.
There was no impact on service at the MBTA, but the bus and commuter rail real-time tracking data available to riders was unavailable for part of Friday morning. It was eventually restored.
The cybersecurity firm CrowdStrike said the issue involved a defect found in one of its content updates for Windows hosts. The issue thought to be causing the outage is not a security incident or cyberattack, the company said.
"The issue has been identified, isolated and a fix has been deployed. We refer customers to the support portal for the latest updates and will continue to provide complete and continuous updates on our website," the company said.

Though leaders with Frontier, according to Reuters, said they were in the process of resuming normal operations late Thursday night, and that their ground stop had been lifted.
This comes after Frontier canceled 147 flights and delayed 212 others Thursday, according FlightAware.
The affected airlines said in a statement they are working to resolve this issue.
Issues at RMV, MBTA
Gov. Maura Healey's office says that while there's no impact on MBTA service, Commuter Rail real time train location and arrival prediction information were unavailable. This technical issue is also affecting boarding information at Boston stations.

Boston EMS says they were dealing with some system issues, but their 911 calls haven't been affected, adding that their services have been and continue to be available.
The Department of Public Health is working with hospitals to go to downtime procedures and continue to provide care, Healey's office said, adding that the department's Operations Center in Marlborough is taking calls from healthcare providers.
