The agency said at about 11 a.m. that it fixed the router issue and the locations are now back up and processing customer transactions.
The DMV had tweeted about two hours prior about the technical problem. It recommended that customers take care of DMV business online or at self-service terminals.
Some DMV field offices are experiencing technical difficulties that may affect transactions. We apologize for any inconvenience and remind customers of other ways to do DMV business online, at self-service terminals and with our business partners: https://t.co/tQXkdiNQ5Q.

There's no word on which specific locations were affected.
In recent months, the DMV has been working to reduce wait times. At an office in Costa Mesa, people were complaining of long lines amid the announcement.
