Telstra's recently troubled mobile network was tested again on Sunday as customers used a free data day - offered as compensation - to download and stream at record rates.

Customers downloaded 2686 terabytes of data - equal to 3.4 million HD movies - up 46 per cent from 1841 terabytes downloaded on a previous free data day offered on February 14.

Sydney resident John Szaszvari was responsible for an incredibly impressive amount of that.

The 27-year-old amassed a grand total of 994GB of data usage on Sunday after he connected his laptop to his LG G4 phone via Wi-Fi hotspot and began downloading at speeds of close to 180Mbps.

He also took advantage of the opportunity to upload backups of personal files, photos and videos to the cloud.

It was a mission so impressive that Chief operations officer Kate McKenzie equated it to a typical user's downloads over 40 years.

Mr Szaszvari said that his quest to begin downloading 24 seasons of The Simpsons, 14 seasons of MythBusters, the ENTIRE Wikipedia database and a “lot of random other stuff” was born from his hobby of collection movies and TV series.

"Believe it or not I actually intend to watch it all – it's going to take a while but at least it's ready on demand," he told Fairfax.

"It's always movie/TV night at my house at the moment.”







Mr Szaszvari also totalled more than 425GB on Telstra’s first free data day in February - a feat that allowed him to download all 25 seasons of the Discovery Channel’s How It's Made and all seasons of Stargate Atlantis, which he is slowly but surely getting through now.

"I'm thinking two Simpsons episodes per evening for the next foreseeable while to remind me of when I was a child,” he said.

Telstra, which has around 16.9 million mobile customers, has given away free unlimited data on a number occasions as apologies for recent major mobile network outages.

The carrier's reputation as Australia's premier telco has been tarnished by three major network problems in the past two months.

Telstra suffered a nation-wide network outage on February 9, followed by another major outage on March 17 that left around half of its 16 million mobile customers unable to make calls or go online.

A third incident, affecting service to around 500,000 of its pre-paid customers, occurred at the start of March.
