On Sunday evening, SVT had major problems with its app and website, and it was followed up on Monday with a shorter similar disruption during the morning.
Tuesday's technical problems, however, were not due to an attack. This time it was a handling error, says SVT's press chief Camilla Hagert to TT.
At the next broadcast window at 07.33, the problem was resolved and the local news was broadcast across the country.
SVT has described Sunday's and Monday's disruptions as a combined overload attack against the public service company.
Since SVT is part of the total defense, the Swedish Civil Contingencies Agency (MSB) collaborates with the public service company to investigate the attacks.
The one we had on Sunday evening is the largest SVT has been affected by, said SVT's technical director Adde Granberg to SVT News on Monday.
Corrected: In an earlier version, incorrect information about an MSB meeting was presented.
