From the DMV:
“District of Columbia Department of Motor Vehicles (DC DMV) reports that due to today’s cyberattack against the servers of an external major regional DNS host, which is impacting other major websites throughout the East Coast, DC DMV currently cannot accept credit card payments for driver and vehicle services transactions. Therefore, customers are encouraged to use cash, checks, or money orders at its Service Centers.
The attack is not against the District of Columbia Government.
DC DMV will notify the public once the credit card services are available. Detailed information about the agency’s services is available online at www.dmv.dc.gov. We apologize for the inconvenience.”
