Maine.gov website

The state of Maine's government website was briefly knocked offline earlier Monday due a "denial-of-service attack," a spokesperson for the state said.

"Attacks to high-profile government websites are very common, and a thorough investigation is underway. The important thing to note is that this was in no way a security breach, and we currently have no evidence to suggest that any personal information has been compromised," said Alexander Willette, director of communications for the state in an email to CNBC.
