Pennsylvania's state government websites are back online after being dark for nearly three hours, but the tax-day outage is prompting a postponement of the filling deadline.
"In light of that outage the Department determined in the interest of customer service it is appropriate to not impose penalties or interest on any personal income tax returns so long as it is filed by midnight today, Tuesday, April 16th," said Pennsylvania Department of Revenue spokesperson Elizabeth Brassell.
Pennsylvanians were unexpectedly unable to file taxes online for a few hours or get tax forms online or help from its online customer service center.
The Monday afternoon outage affected many of the departments under the governor's jurisdiction, including the Revenue Department on the last day to file taxes.
The outage began around 1:30 p.m. and was resolved at about 4 p.m. Officials couldn't say why it happened, just that it wasn't triggered by a cyber-attack.
