The Polish public broadcaster TVP has suffered a massive power outage, resulting in all its channels going off the air.
The incident, which took place on Saturday, February 15, was resolved after around two hours.
TVP says it was not linked to any changes made to its digital terrestrial broadcasting made at midnight from Friday (14th) to Saturday (15th) February.
Local reports meanwhile say there was no connection with a strike by TVP employees and that an audit of power systems will take place in February 17.
The last such outage took place in the first half of the 1980s, when TVP had only two channels.
