Millions of users have been hit by a mass internet outage affecting Verizon Fios coverage on the east coast.
Reports of outages flared between midnight and 2am EST, prompting rife complaints on social media.
A spokesperson for Verizon, responding to a user from Ashburn, Virginia, confirmed: 'There is either an outage or network maintenance impacting your area. We don't have full details just yet.
'Our apologies for any inconvenience this is causing. We're trying to get all the information from our network team so we can provide you all an update.'
More than 40,000 instances were reported early this morning, up from fewer than 100 before the spike.

Fifty-three per cent of users reported issues with 5G Home internet, while 33 per cent had issues with landline.
Fourteen per cent reported a total service blackout.
